Please tag your jars as Fabric, I installed it from the app expecting it to be Forge. The app only shows mods that are tagged as the same modloader as installed in the instance.

Thanks for the heads up! The files should all be flagged with Fabric, but looking at them now it seems some specific releases missed the flag. I'll make sure to add them where applicable.

no problem, I always report these to make sure it's convenient for all of us modpackers haha, thanks :)
