Something's not going right with the sync in the latest prerelease version... Or am I doing something wrong?

- Made a backup with version 5.43
- Cleared database
- Installed version 5.44 pre 3
- Restored backup
- Last step in the restore process: sync to online collection, using the database as the master
- Process a few title updates before I close the program and switch off my computer
- The next day, I start up the program again, and there's a popup that changes have been made. Would I like to sync my collection. Yes, why not?

Now here's where it goes wrong: All the titles are now loaded (where from? The online collection?) and merged into my local database, resulting in duplicate entries of EVERY title.

I cleared the database, and started a database restore again, synced to online collection, exit the program, restart the program, attempt another sync: same thing. All my entries are duplicated.

Is this an error, or am I doing something entirely wrong?

Edit:
I did another collection restore, and selected 'replace collection in the online database with data from the restored database'. Everything is downloading from the online database. This is not right.

Pre Release 4 has the same behaviour. At the start, my database had 4500-something titles and my online collection had 4555 titles (I think they were about the same). Then I started the sync with the database as the master, and all the titles are downloading again.

After 4 hours of syncing (yay for having a large collection) I had to cancel, because I have to leave for a short trip. It's not possible to halt the initial syncing process either. The app just closes when you click on the X in the 'Synchronize Online Service' popup screen, and when you restart the app, the sync continues where it left off. You have to ride it out. But right now, my restored database has 9108 disc titles and my online collection has 4555 disc titles. Everything is listed twice in the desktop app.
