Plex shows active Tuner after stopping Watching and recording

Hello,

after some problems before the DVR-Feature works fine on my Synology DS918+ And I can Stream and Convert a lot of Streams at the same Time.

If I stop the Streams , at the Status is the message “Recording Live TV”. In Settings under Live TV and DVR the Tuner shows 8 Tuner, 1 Running recording. Is there a chance to locate the Problem? The Usage of the Network and CPU activity dosn’t show, that the NetWork-Tuner sends Data to the Plex-Server. At the WebInterface of the NetWork-Tuner I can’t see any streaming activity too.

Plex is the Version 1.11.3 running on a Synology DS918+. My logs are Attached.
