Classified Member (User Role) can't add Events

I have the classifieds and events+ plugins installed and found that a classifieds member can't add any event. A page is shown, telling him he hasn't the right to do so. The following roles are configured:
Classifieds -> add as "Classifieds Member"
Events+: Selected the "Classifieds Member" from the "Event Capabilities" drop down list and enabled all rights (except to delete other's events).
A member with the "Subscribers" role with the same settings is able to create an event.
As far as I understand a "Classifieds Member" should also be able to create an event, but he can't. Any idea?
