When you complete any mission in myriad island the pink marker don't go and it don't show in stats?

If the pink marker doesn't disappear after completing a mission on Myriad Island, it might be a glitch in the game. Restarting the game or re-entering the area may resolve the issue. Additionally, check for any updates or patches for the game, as developers often fix such bugs in later versions. If the problem persists, consider reporting it to the game's support team for assistance.
