DVR Recording Schedule issue

Hi,
When I specify a show to record in the Program Guide the Plex DVR is creating several recordings in the schedule calendar no related to the show I specified to record.

See the example below:

I tried deleting my DVR in “Settings->Server->DVR (Beta)->Delete DVR” and adding again my HDHomeRun Prime and updating the EPG but the problem continues, also I uninstalled Plex, reinstalled and configure everything again but I get the same problem.

My configuration is:
Windows 10 Prof.
Plex Server Version 1.7.2.3878
HDHomeRun Prime
Model: HDHR3-CC
Device ID: 1321A1F1
Firmware: 20150826

Any ideas how to resolve this problem?

Regards
