MDG/Profile: Generalization of Stereotypes seems not to work as expected

[dge98753]

Hello,

I try to extend the model with a custom profile.
I would like to create a new "ArchiMate3::ArchiMate_BusinessRole"
In the profile diagram of my MDG I link my new Stereotype (named "MyRole") to a Metaclass Stereotype "ArchiMate3::ArchiMate_BusinessRole" using the "Generalize" Link.

All seems to be great.
But we in the model, when I try to quick link a "MyRole" to a "ArchiMate3::ArchiMate_BusinessActor" AE refuse the link.
I was wondering that it will show me the same possible links than with a  "ArchiMate3::ArchiMate_BusinessRole", like "Assignment".

Do you have some ideas of what could go wrong ?

Best Regards,
Damien
