It could possibly mean you have another object behind there (i.e. Label, TextBox, etc).
If you go into Design Mode, can you select it (and them move or delete it)?
What happens if you move your "ACTIVE..." and "Booking..." objects (labels, images, whatever they are) out of the way?
Do you see any objects underneath them?
There isnt anything underneath them

I don't know what else it could be off the top of my head.
You could always try uploading your database here, so people can take a look at it to see if they can tell what us going on.
