General :: Tasker Profile - Auto Mute In Meetings (Gmail / Calendar)

I've tried for several hours to let this profile work, no success so far . In Tasker I've created the following:

- New Profile , State , Calendar Entry
Title: MuteonMeetings
Location : Empty
Description : Empty
Available : No / Yes (Profile 1) (Profile 2)
Calendar : Google : + (Gmail-adress). I've tried basically all my available Calendars (individually also)

- New Task, Audio, Silent Mode
Mode : On / Off (Profile 1) (Profile 2)
If : (select option) Is not selected. Maybe I need to use it??

And another Task that shows in Text-Plain that the meeting this start (Flash)

And this task is linked to the profile.

I've created another profile and task with the opposite values, to UN-mute automatically after the meeting is over.

I made some test--appointments and synchronized my calendar on phone. When the time of the event hits, nothing happens. Even in the Tasker Log , it says that the profile and task are not started . When I run manually both of the created Tasks for Mute / Un-mute it works. It looks like that Tasker is not checking my Calendar (Time/Events) etc.
