So if you have the setting enabled for twitch mods to sync to deepbot, then it would sync all mods from your twitch channel. It gives any mods, the deepbot mod level 1 by default. So if you unmod someone from your twitch channel, you also need to remove it manually from deepbot.
So possible explanations:
- The user got a name change and may have been a mod
- Maybe you made them a mod by accident
- Maybe you got a name change recently and it had something to do with that?
- I would check your connections under you settings and disconnect anything you don't use anymore or is gone.
