How to block Teamviewer using Application Filter

Hi,

i try to block Teamviewer applying a specific application filter to my LanToWan rule.

I select Teamviewer Conferencing and Teamviewer File Transfer as Application filter criteria.

Team Viewer is still working. 

I check the patterns which are all updated.

Searching in Sophos Community i didn't find any indication which can help me.

Can someone show to me how can i block Teamviewer?

Thank you in advance
