EPG selection for channel changes

Hi.

I have only enabled 15 channels on my HDhomerun as there are only EPG available for 15 of our channels at this time (And there’s no point in enabling the rest as you cannot record channels without EPG… nudge nugde, know what I mean plex?)

Anyhow every few months all of a sudden Plex just changes the EPG selection for a given channel - without notice, and I have to manually correct the EPG for about half my channels. It used to happen when I updated the Plex Media Server Version, but lately it seems to have been happening on it’s own. I have not confirmed if it coincides with a reboot of my NAS (Running Plex on QNAP NAS), but that could be the case.

Is anyone else experiencing this, and is there an explanation?
