Deactivation - Call Redirection Problem

I installed and used TASKER first yesterday. Therefore  i created a profile (if telephone rings) that a task call redirection (german: Rufumleitung) will start.

That worked perfectly. But then after testing i wanted to manually disable therefore i  moved the toggle to grey on profile (if telephone rings) but recognized that android holds the message that all calls will be redirected.

I testet it and it is true, also with deactivation the option still stays and all calls are redirected. I never made other setting on android therefore therefore i must come from tasker...

Now is this a bug or how to enable disable using this profile...?

Regards.
