My scrollview doesn't scroll entirely

Solved : The problem was that I used the same Vector2 for both the two scrollpositions.

I got two scrollviews where the content are defined by a calcheight on two different strings, for one of them, it does work perfectly but fur the other one the vertical scrollbar is being stuck at a certain point.

Here is my code : void OnGUI () { void OnGUI () {

         GUI.skin = guiDropDown;
         GUIContent contentPropos = new GUIContent(stringPropos);
         float heightPropos = guiDropDown.label.CalcHeight(contentPropos,Screen.width-20-(Screen.width/4));
         Debug.Log(heightPropos);
         Rect rectProposSV = new Rect( Screen.width/4,-Screen.height/2,Screen.width-20-(Screen.width/4), heightPropos);
         
         // dropdown a propos
         GUILayout.BeginArea(rectDropdownPropos.rect);
         GUI.Box (new Rect(0,0,Screen.width,Screen.height/2),"");
         guiDropDown.label.fontSize = 30;
         guiDropDown.label.alignment = TextAnchor.UpperRight;
         guiDropDown.label.padding = new RectOffset(5,0,5,0);
         GUI.Label(new Rect(0,0,Screen.width/4,150),"A propos de \nNG Promotion");
         guiDropDown.label.fontSize = 12;
         guiDropDown.label.alignment = TextAnchor.UpperLeft;
         scrollPosition = GUI.BeginScrollView(rectDropdownProposSV.rect, scrollPosition, rectProposSV);
         GUI.Label (rectProposSV,stringPropos);
         GUI.EndScrollView();
         guiDropDown.label.fontSize = 15;
         guiDropDown.label.padding = new RectOffset(0,0,0,0);
         GUI.Label (new Rect(Screen.width/4,Screen.height/2 - 44,Screen.width-(Screen.width/4), 44),"Coordonnées :");
         if(GUI.Button (new Rect(Screen.width/4+150,Screen.height/2 - 44,Screen.width-(Screen.width/4), 44),"Email : contact@ngpromotion.fr")) {
             Application.OpenURL("mailto:contact@ngpromotion.fr");
         }
         GUI.Label (new Rect(Screen.width/4+450,Screen.height/2 - 44,Screen.width-(Screen.width/4), 44),"Tél : 04 67 55 22 33");
         GUILayout.EndArea();
         
         GUIContent contentMentionsLegales = new GUIContent(stringMentionsLegales);
         float heightMentionsLegales = guiDropDown.label.CalcHeight(contentMentionsLegales,Screen.width-20-(Screen.width/4));
         Debug.Log (heightMentionsLegales);
         Rect rectMentionsSV = new Rect( Screen.width/4,-Screen.height/2,Screen.width-20-(Screen.width/4), heightMentionsLegales);
         
         // dropdown mentions légales
         GUILayout.BeginArea(rectDropdownMentions.rect);
         GUI.Box (new Rect(0,0,Screen.width,Screen.height/2),"");
         guiDropDown.label.fontSize = 30;
         guiDropDown.label.alignment = TextAnchor.UpperRight;
         guiDropDown.label.padding = new RectOffset(5,0,5,0);
         GUI.Label(new Rect(0,0,Screen.width/4,150),"Mentions\nLégales");
         guiDropDown.label.fontSize = 12;
         guiDropDown.label.alignment = TextAnchor.UpperLeft;
         scrollPosition = GUI.BeginScrollView(rectDropdownMentionsSV.rect, scrollPosition, rectMentionsSV);
         GUI.Label (rectMentionsSV,stringMentionsLegales);
         GUI.EndScrollView();
         if(GUI.Button (rectGuideUtilisation.rect,"Guide d'Utilisation")) {
             LeanTween.move(rectToolbar, new Vector2(0f,0f), 0.25f);
             LeanTween.move( rectDropdownMentions, new Vector2(0,-Screen.height/2), 0.25f);
             displayMentions = false;
             displayGuide = true;
         }
         GUILayout.EndArea();
 
 // at a certain point i use itween to drop down the area where the scrollview is
 
 }

So the // dropdown a propos works but not the // dropdown mentions légales

I can provide screenshot if you don't see what the problem is or if I'm not understandable :D

Hope you could help !
