I updated from 1.6 to 1.8. Then I changed myawards plugin compatibility from 16 to 18 and it seems to work but old awards cannot be viewed on post author bit. If I grant an old award now it is shown though plus it show also the old one granted before the update. But i can't do this for every user.
How to make awards granted before the update to be shown?

I still have no idea how to solve this...
