ScrollView runtime Instantiating button in the content

Hi guys, I tried to Instantiate a button into the content of a scrollview, after i ran the game the button goes massively wrong positioning and scaling, even though there is a Verticle Layout group to the content and i gave the button a Layout Element, I tried then to put the button manually and it works normal even in runtime

here's some screenshots :

Script Instantiating:

Manual Instantiate :

Script :

         foreach (MatchDesc match in matchList.matches)
         {
             GameObject _roomListItemGO = Instantiate(roomListItemPrefab);
             _roomListItemGO.transform.SetParent(roomListUI);
             _roomListItemGO.GetComponentInChildren<Text>().text = match.name + " (" + match.currentSize + "/" + match.maxSize + ")";
             _roomListItemGO.GetComponent<Button>().onClick.AddListener(delegate () { NetworkManager.singleton.matchMaker.JoinMatch(match.networkId, "", OnJoinInternetMatch); } );
             
         }

Edit : The button works perfect on resolution of 1920 x 1080 and all other wide resolution but for the others not Even though i have a screen
