position image in app desinger before after full screen

Hello,

I have been working in an app in app designer and I can not achive to scale correctly for ONE image. the rest works correctly,

issue I placed an image inside a button, (I did this for 4 buttons) 3 of them works correctly (the image stays inside the button) but in one case the image goes outside of the button.

I notice that app designer decide the scaling for from the aligment that we used before in the design view, but I can not succesfully achive to keep the image inside the button even by grouping it with the button. (the last button is the problem in the right down part of the window)

any help?
