When a parameter is placed directly within a material it's group assignment works. The parameter is listed within its group in material instances.
This does not work with parameters that are created within material functions though. Their group setting is ignored and they're placed in default groups.
See the attached images for a repro.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-5603 in the post.
