Non-reproducible. I've just tested with several devices and I have no problem with the database after saving from KeePassDX.

I don't think the problem lies with the app because :

• The engine is different between KeePassDX and KeePass2Android, so I don't see why there would be the problem on both apps at the same time.
• Plugin keys remain available in the database without any problem.
• Your problem has nothing to do with a Yubikey, it's an unlock mode, it doesn't affect the integrity of a database.

It's possible that the problem is due to synchronization, so I'll leave you to look into this.
