There seems to be a cosmetic bug with challenge tracking appearing twice:

Reproduced by:
- Enable the Guardians global event
- Enable challenge tracking for Day 4
- Play the game
- Close the game in the open world
- Restart the game (doesn't matter whether it's immediately or a few hours later)
Expected:
- active challenges only listed once
Actual:
- active challenges listed twice
Additional information:
Opening the global event details shows that challenge tracking for the day is OFF

"Enabling" tracking removes the duplicates, and challenges are still tracked.
