What linespacing did you specify for the check box field? A bug was recently acknowledged where check box fields with line spacing other than 1 (single spaced) that may be a factor here.
For More Information see: Issue with line spacing in Checkbox sets
This is one of many acknowledged bugs that can be found in the Known Bug List thread here in the Report an Issue section of the forum.
It can also be downloaded as a database file from: http://www.4shared.com/file/8orL8apk/FMP_Bugs.html

Thank you for your post.
I'm having trouble visualizing the problem without a screen shot. Can you post a screen shot?
Perhaps it would be best if you sent in your database file, and I'll try to replicate the issue here. Check your Inbox at the top of this page for instructions where to send the file.
