[2021] Some Battle Pass Challenges Don't Track or Track Inconsistently

The weekly BP Challenges seem to track inconsistently or they don't track at all. Last week, one of my challenges was 40 eliminations and it got stuck at 38/40, even after having a 5 kill quick match game. After an hour or so, the challenge ended up tracking those kills and completed the challenge. This week, I am having the same problem (5 explosive eliminations challenge), however, it has been 2 days since I 'completed the challenge' and the challenge is still at 1 of 5 kills.

For those that are wondering, I play Cav, down someone and throw an impact to kill them which has completed many explosive kill challenges in the past, both BP challenges and Ubisoft Connect challenges. I contacted support but they haven't responded as of yet so I thought I'd post here in the hopes of receiving a response quicker.

Thanks in advance.

P.S. Is there any information on the "Free E-Sports pack" that we are meant to receive this season. It's not a big deal or anything but I would still like to know if it's still a thing or not.
