Is my task force tag bugged or is this display showing something else?
Solution 1:
This is likely a bug. If you go to your Task Force's home page, the URL is:
https://ghostreconnetwork.ubi.com/en-US/task-force/profile/55650/XboxKlubben
Notice that the number after profile/ is 55650, the same number you are seeing in the brackets. If I had to guess, the Xbox version of the game may be interpreting the code differently or incorrectly, and thus is pulling the number of your Task Force and not the name.
I've also found a GameFAQs post of someone experiencing the same issue as well as an Ubisoft Page.
