Completion of dark hunters side quest not registered

Platform, device and operation system
Android, Samsung Galaxy M10

What were you expecting to happen, and what actually happened
*The side quests of dark hunter are not registered as completed. In version 0.39 the side quest completion are not shown. So I could not check. In version 1.01 it is a goal which in my case is now shown as not completed.
But I finished the main story now with 10 heroes and every side quest. The 10th last week. *

How often does this happen? When did it begin happening?
I finished every side quest before making the final fight. I always had my hero already upgraded on level 50. I am pretty sure about that because the 10th hero was last week.

Steps to make it happen again
Possibly this has something to do with the hero level? Because it was 1. Already 50 not 49 or 2. Not 50 but 50(168)?

I can confirm two others that have updated and have the same issue.
