Properties tab not fully visible when I open project from 5.5 in 6.0

My team recently upgraded from Captivate 5.5 to 6.0. One of us encountered a problem when she opened a file created in 5.5 in 6.0. The properties tab window did not apprear to be sized correctly. When my co-worker tried to insert an image button, there was no file folder button to choose an image. It looks like it is just off the screen, but we can not figure out how to get the button back. We tried resizing the properties tab and that did not work. The issue does not occur when we start with a blank project in 6.0. Can anyone help?

The first picture below is what my co-worker sees. The second is what we normally see. The part highlighted in yellow is what is missing.
