Tag groupping in extended stereotypes?

[Mauricio Moya (Arquesoft)]

I created a profile with stereotypes includig tag groups. Then, I created a new (child) stereotype extending (with a Generalization) the stereotype with tag groups. But the child stereotype, when using the profile, doesn't include the tag groups. The tags are plain-shown, not in groups as the father stereotype.

Any idea or suggestion? is this possible to do?
