Rerolling Challenges Doesn’t Work When Challenge Is Tracked

As the title says, rerolling a challenge doesn’t work if the challenge is tracked (pinned). I used 3 out of 5 of my rerolls while the challenge was tracked, and nothing happened. After untracking the challenge, the reroll worked correctly.

Steps to Reproduce:

1. Track (pin) a challenge.
2. Attempt to reroll it.
3. Observe that the reroll doesn’t work.
4. Untrack the challenge and try again — reroll works as expected.

Expected Result:
Reroll should work regardless of whether the challenge is tracked or not.

Actual Result:
Reroll only works when the challenge is untracked.
