Achievement not showing up in tavern

Hello,

I've completed both Portal Protector and Nightmare Portal Protector achievements, yet they're not showing up as trophies in my tavern.

I've tried the following to possibly solve this issue on my own:

- re-enter tavern
- complete the challange again
- verify game cache
- re-download the entire game

None of these steps fixed my problem.
Any help from you guys on what to do would be greatly appreciated!
