Are you running version 3.1.9 on both devices? If I had to guess, there is something going on with the "version" field for the annotations. If they were created before version 3.0.0, but the version field indicates they were created after 3.0.0, that mismatch would cause them to render incorrectly. I can verify this if you email me a copy of the database file (mobilesheets.db). It would be best to get that file on the device they are now rendering incorrectly on. If it's an Android device, you'd need to enable Settings->Storage->Expose Database and then you can find the database in the storage location.
