Stat trackers from loot ticks

I own every single stat tracker and I’ve had each one since they were all available. However I’ve been recieving trackers I already own. At first I thought maybe I missed a couple on new legends but I went through every single legend and confirmed I own every single stat tracker and yet I still continue to get 1-2 stat trackers each time I’ve opened a loot tick. This has happened on over 10 loot ticks ranging from regular loot ticks to the event ones. Is this a know issue and how can I go about getting my proper rewards from loot ticks such as crafting materials or cosmetic I do not already own.
