"Activate a 6 unit trait bonus" mission not recording/registering/counting a successful completion?

Going to start by pasting essentially what I left in the official bug reporting submission page that is linked from the client itself:

Steps of what happened:

​1. Played a game of Teamfight Tactics(TFT), with the intent of trying to complete this week's "Activate a 6 unit trait bonus" mission.
2. Played one normal game of TFT, gathered 5 units of one trait bonus (in this case, Glacial) and then added a Frozen Mallet to one of my other, non-glacial units (as Frozen Mallet makes one unit a glacial that is not already).
3. I took the time to verify my gold 6 Glacial units trait was active before my next round of combat/gameplay -- which I assumed gave me a complete mission. 4. After the game's information was recorded and my other active mission updated (for playing 12 Void units or 20 assassin units), my "Activate a 6 unit trait bonus" mission remained incomplete. 5. I believe this also occurred to me for an earlier mission (weeks ago?) which asked you to complete the same task, 3 times. I recall having to complete the task 4 times instead.

Expected/Actual Result(s): Expected Result: My TFT mission is registered as completed when I took the time to alter my playing strategy specifically to complete it, and did. Actual Result: The game/client counted progress for one mission but not another.

(the preview is organizing this list as: 1, and then 1-4 in a sub-list instead of 1-5 -- sorry if this happens in the actual submission)

If I can't complete this mission, there may not be a way for me to complete the remaining TFT Beta Pass missions and left I'm stuck between mission 12 & 13. I had a similar problem with the first Beta Pass: where my daily "orb of enlightenment" didn't come off cooldown for more than one consecutive day (on multiple occasions) and as a result, I was unable to complete the first Beta Pass's final mission. As a result, I'm finding this extra frustrating. If I'm playing TFT this weekend -- specifically to complete a mission -- but am also not allowed to complete the mission, what's the point in me playing at all?

As an aside: bug reporting for TFT through the "Report A Bug" feature (linked in corner of the client) is genuinely terrible.
There are no specific options to explain for Teamfight Tactics-related problems.
