Beast Awakens tome challenge not tracking

This is on PC after the last patch. I tried getting this challenge 3 different times, 2 of them with infinite tier I Michael, and even after getting 10+ undetectable hits on the challenge doesn't get completed at the end match.

The third time I tried to get it with only beasts of prey for undetectable on Bubba, and even after 8+ hits it still didn't get completed.

All 3 games were on closed maps (Hawkings, the Game and Midwich)

Steps to reproduce: Just select the challenge and attempt to complete it as normal
