Input.GetKeyDown gets registered twice in row

Hello, am trying to a make a turn based RPG and currently working on the battle UI. The player gets a first menu to pick his general move from (Attack, item, talk, run), if he chooses attack it leads him to a menu with the different moves the character has. My problem is that (Input.GetKeyDown(KeyCode.W) seems to instantly pick the attack menu AND the first move on the list in the same button press. thanks in advance.

 private void Update()
 {
     if (state == BattleState.PlayerAction)
     {
         HandlePlayerAction();
         
     }
     if (state == BattleState.PlayerMove)
     {
         HandlePlayerMove();

     }
 }

 private void HandlePlayerAction()
 {
     int prevSelection = currentaction;
     if (Input.GetKeyDown(KeyCode.DownArrow))
     {
         if (currentaction < 3)
             currentaction++;

     }
     else if (Input.GetKeyDown(KeyCode.UpArrow))
     {
         if (currentaction > 0)
             currentaction--;
     }
     if (prevSelection != currentaction)
         hud.UpdateActionSelection(currentaction);

     if (Input.GetKeyDown(KeyCode.W))
     {
         
         switch (currentaction)
         {
             case 0:
                 //Attack
                 PlayerMove();
                 break;
             case 1:
                 ;
                 //Item
                 break;
             case 2:
                 //Talk
                 break;
             case 3:
                 //Rung
                 break;
             default:
                 Debug.Log("Bug: selectionUI");
                 break;
         }


     }

     int prevSelection = currentmove;

         if (currentmove < playerUnit1.Monster.Moves.Count - 1)
             currentmove++;

     }

         if (currentmove > 0)
