Sounds like a database issue.  CLPACK utility may be able to fix you up, look in Lacerte Tool Hub.

Also, sometimes you can do things like Ctrl+A(dd) a throw-away record, type in garbage 'Esc' out to the Client List (forces Lacerte to 'save' that client), go back in to page2/Dependents, and Ctrl+D(elete) the throw-away.  That has fixed up a number of oddities for me at times.
