Ziggo NPO1 ZuidHolland EPG has a timeshift of 2 hours...

I have one channel (Ziggo NPO1 ZuidHolland) with EPG data with a timeshift of 2 hours (a program that starts at 20:00 is shown with a starttime of 18:00 in Plex). Is this a problem of the GraceNote EPG provider or a problem in Plex? I have this problem since one or two days. Before, I didn’t had this problem.

Can anyone in ZuidHolland check if he/she has the same problem?

Problem solved since the last two weeks. Probably a problem with GraceNote.
