Missing new recordings

Hi , I have the following problem , new that are scheduled in tvheadend are not showing in Kodi. When I look in the logging of kodi is see the following : AddOnLog: Tvheadend HTSP Client: pvr.hts – malformed dvrEntryAdd/dvrEntryUpdate: unknown priority value 6

Does anybody know what to do to fix this ?

HTSP Client 3.4.24
Kodi 17.3
