Videos in Group before/after Group Association switch?

hi SI Team

I have a post here in the Group “Basic Access”:

http://finalbug.net/blog/entry/547-fcp-x-subtitles-the-missing-webinars-02

I posted 4 videos in this group:

http://finalbug.net/videos/group/21-basic

If I decide that this Blog post should really go in the group “Intermediate Access” I can change the group with which it is associated from “Basic Access” to “Intermediate Access”

This is all great but the videos do not move from the group “Basic Access” to “Intermediate Access”

Surly this is not the way that things are meant to work?

FYI when I switch back from “Intermediate Access” to “Basic Access” the videos appear again.

please advise

thanks

Paul
