Deleted List can't be removed from the addon config

[bdshields]

I had 2 lists selected for sync which worked fine. I then deleted one of those lists on my phone, but I can't remove that list from the addon config. In the "Lists to sync" field, it just appears as (what i think is) the hash identifier, and can't be unselected or deleted. I'd be happy with a manual workaround to remove that list, but don't know where stuff is stored.
