Restoring backup

I create backups of Basecamp on a regular basis (File > Backup). Now I want to restore (File > Restore) a backup, but I end up with an 'empty' Basecamp list. The back-up file Basecamp.Backup has a size of 114 Mb.
FYI the backup takes a few minutes to complete, the restore is just a matter of seconds. And yes, the backup file is created with the same version of BaseCamp as the version I am restoring to.
BTW, when I create a new backup after the restore, the new backup file has a size of 58 Mb, even when the list is empty.

What is going wrong (ow what am I doing wrong?
Any help is greatly appreciated. Otherwise, I am losing some hundred hiking tracks ...
