Below are a few steps to troubleshoot this issue:

1. Check to see if thelock aspect ratio option for the objects, if checked, is locking the objects into an incorrect size
2. Make sure the objects are correctly positioned and are not overlapping
3. Check the grid and guides settings to make sure they are not forcing objects to be in an overlapping position
4. If you’re using hyperlinks, make sure the link is correct and the text being used is large enough
5. Check for object alignment issues
