If this happening in a list view, check the setting in the Layout Setup dialog re Delineate current record. It may depend on where they are in the list depending on this setting.
No this is happenning in Detail view
Wwill re Delineating the fields in Detail view solve this problem?
I don't recall messing with that setting for a Form view layout, but give it a try, and let us know.
If you haven't got it working soon, try posting a couple of screengrabs of the correct and bad views so we can see what the problem looks like to you. Or even a copy of the file for testing to see if it's reproducible. For that testing, we'll also need your OS and FM version details so someone with the right configuration can try it.
