Can't upgrade team in Dungeon after using valour for slot uograde

This seems like a duplicate / repeat of the same thread here:

Army upgrade bug

I just encountered this same problem. My thaurissan was level 19, dungeon was granting +2 level. I had applied a valor upgrade to my thaurissan which put him at a bonus +4 slots. Once I completed the dungeon 19 + 2, I ended up at 21, which filled all EXCEPT 1 bonus upgrade in army slot. Next dungeon run considered me at level 23 instead of 22, as if it counted the bonus valor as part of the base bonus level. Completing the dungeon at level 23 gave me 150gold instead of my last army upgrade …

It is indeed something that probably was not taken into account and a bug that crept in when the valor upgrade got introduced.
