getButton always return true

When I call getButton with same button in input module in code. It's always return true, even i didnt click that button and i already disable all interactable ui element. If I change to different button that not same button in input module,it's work fine.

so if i want to getButton the same button in input module. What should i do.

edit add some code

 if(Input.GetButton("Ok") && !submitClicked){
     submitClicked = true;
 
     foreach(GameObject obj in target){
         obj.GetComponent<BaseCharacterObject>().Selected = false;
     }
 
     action.Target = target.ToList();
             
     uiState = UIStateMachine.EndUIState;
     submitClicked = false;
 }

Button "Ok" is the same as Submit button in Standalone Input module When i run ,Input.GetButton("Ok") is always return true even i didnt press it
