Upfront problem with arranging images

Hi I am trying to arrange 3 images and underneath them 3 buttons, but somehow i am not able to make them all three the same size I do not know why they always resize and one has a white background?
It in in the global region (top 3 casinos) I tried cloning resizing but nothing works I have had this issue in the past with Upfront, how can I fix that?
thanks and regards
