Challenges/assignments not appearing after completing basic level assignments

I've completed the basic training assignments for each class but the proficiency and master assignments never generate. I've played on PS4 prior and received/completed them just fine. Have played over 20+ hours on PC since completing the basic ones and nothing new has populated. Have even completed a majority of the epic weapons assignments to see if new space was needed for other assignments. No luck. Have researched MANY forums of users experiencing the same issues, some reported as early as 2017, and none were ever provided a solution. Please help, this is a major game deficiency and severely determines my interest in continuing with gameplay and is forcing me to reconsider purchasing Battlefield 2042, if the game devs can't fix a simple bug or provide a meaningful response to its gamer base within a four year timeframe.
