Issue with push button userdata

Hello.

I am trying to enable a push button to exit a loop if its pressed and decided to user the buttons "UserData".

So I initially set it to 0.

set(handles.btnStop, 'userdata',0)

in my loop, i then check the status of this with an if statement

 if get(handles.btnStop, 'userdata') % stop condition
		        break;
 end
 

In a stop push button I set the user data to 1

 set(handles.btnStop, 'userdata',1)
 

But Im getting a strange result.

when I check what the userdata is berfore I go into the loop (via set(handles.btnStop, 'userdata',0)), I see its a cell array with 2 elements:

ans =
  2×1 cell array

    {[0]}
    {[0]}
