As some leagues might have more than one commissioner, it is entirely possible that the same league could be renewed multiple times, creating duplicate leagues.
This can also happen to leagues with just a single commissioner, as all leagues can be renewed more than once.
When this happens, it's completely fine to delete any duplicate leagues. Each league is completely independent, so it won't affect the other one.
Deleting a League
Go to commissioner settings
Scroll down to tap on "Delete League"
Enter the name of your league
Tap on "Delete League"
