Since upgrading to version 11 from 10 my buttons are behaving differently on different pages. I have made two buttons of identical size. The first button is the main image, then I select Display/Image Overlayed and I import the 2nd button. On every page the other options on the Display page are identical. On some pages when I hover over the button the image resizes larger than the original image whilst on others it maintains the same size. I can't work it out. I have even tried recreating pages but this still does not solve the issue.
