How can I expose a Material Function category to Library?


I’m having a problem creating a category for my material functions. The checkbox for “Expose to Library” works but the drop down with the name for the category does not, the function always go to “Uncategorized”. Any pointers?

I experience the same problem in 4.15.1 and 4.12.5,but it works on 4.10.hope it can be fixed.
