Kingdom challenges problem

Platform, device version and operating system:
PC Windows 10

Screenshot or image:

What you were expecting to happen, and what actually happened:
Can’t continue Khaziel challenges. It show Tier I - 7/7.

How often does this happen? When did it begin happening?
I don’t know. Other kingdoms has no problem.

Steps to make it happen again
I don’t know.

I have the exact same issue. Khaziel shows Level 1 completed but it won’t roll over to Level 2. It’s the only one that is like that.

No issue here, but I didn’t had all t1 challenges completed prior to the challenge system rework…
