Does the message show up after a reload of the page?

I noticed alot of wierdness adding multiple categories now. I wiped out the entire list and I can’t add multiple subcategories.

Any update on this? I want to push out a mass import of all my users and if this feature is close to working, I’d like to take advantage of it before pushing a bunch of new users to my instance.

Thanks!

This feels like a legit bug to me @zogstrip could it be due to duplicate category titles?

@Jared_Needell, I just pushed a fix 🪲. Can you update to latest and try again?

The issue was that it wasn’t properly working when you remove a category from the list
