Works as intended for me on 1.20.6. Depending on what launcher/modloader you use you may need to completely reinstall for the fix

Should be fixed now

Tested it and it works thanks !

It looks like a bug on our end. No ETA on a fix since 1.14.4 is quite an old version, but the dev is taking a look into it.
