Delete a a personal stereotype without profile

[elr]

Hello all,

I get stuck with an association stereotype  that is wrongly named.
I tried to delete it through UML Type windows but Delete button stays greyed when I select it on the list...
What's the trick ?

Thank you

Have you enabled security?

Yes !! I reopened my model with an unsecured standalone version and the Delete button is active.
  Thank you!"
