Just realized it's happening to a few alternate glyphs too

Hi, I'm designing vietnamese glyphs and seems like KernOn it's not recognizing glyphs like horns or a few others. I have to mannualy add them pair by pair in my whole project as “auto”. What can I do to make this work better?

Me again...
Kern On crashes Glyphs App when I select a glyph to “no kerning”, I tested in multiple files, multiple glyphs, I tried reinstall Glyphs and Kern On. I've already used “no kerning” a lot of times, never had a problem before.

I can send you the file if you want

Ok, I manually deleted it on .glyphspackage and worked.

I tried that, the moment I start Kern On, all User Set pairs are there.

Hello all, I'm using Kern On an ongoing project and I made some bad decisions. I'm trying to delete all the User-Set autopairs and everything else. Start kern on again from scratch. I'm not finding how can I do that.

Not sure if I have a good answer for that, It's my usual workflow and in my mind is easier to organize things after kern on expand, when I do final manual adjustments.

Is it possible to Kern On create groups for everything, even if it is just a one glyph group?
