Juggerduck task not updating correctly

I'm currently working on the limited time Howard (Juggerduck) tasks and have noticed a minor issue.
The first 2 abilities update correctly, but the 3rd one, Ducking Unstoppable, will only update 1 time per fight regardless of how many times it got fired.

I'll still get the task done today. It will just require more fights.
I'm posting this in case it can be fixed soon enough to help others or understand what's wrong to correct the problem for future tasks.
