Is There A Way To Delete Sets In Azure Sets?

I made too many variations and need to clean up the list. I tried deleting sets out of the config file but they still show up for some reason in game after reload.

It doesn't look like there is. Make sure you have AzureSets unloaded, then manually edit the settings file, save it and reload the addon. Trying to edit settings files with the addon loaded will usually just result in the addon overwriting your changes.
