Also problem may be in that information of available updates has not been purged from the database during upgrade procedure. Nest running of DailyMaintenance script should fix this issue. Or you can clean it manually in psa database with
DELETE FROM smb_productUpgrades
DELETE FROM smb_componentUpdates
I have reported this issue to developers. They will fix it.
Thanks for the update. Let us know exactly what DB changes you had to make, if you don't mind. Would be helpful to future users that may run into the issue.
