Tvheadend no longer updating EPG

Hello, I'm new to using LibreELEC and tvheadend so I apologize if I'm missing something obvious or not providing enough information. Exactly a week ago, I set up LibreELEC and tvheadned to receive UK Freesat over a USB DVB-S receiver. The problem is that there isn't any EPG data being listed besides around 15 channels. I've tried re-running the internal EPG grabbers but that hasn't made a difference, I'm not sure what I should attempt to do to resolve this. I'm still able to watch the channels.

With that said, I've read that the Freesat EPG is 7-days in length which would correlate with me losing EPG data exactly a week after setting up tvheadend. Any suggestions on how to proceed would be greatly appreciated. If there's any information I could provide please let me know. Thank you in advance!

Thanks for the help, I really appreciate it. I probably should've posted this in the TVH forums sorry about that. The solution that worked for me is that I added 11425H and 11778V to the mux scheduler. For some reason 11426H wasn't available to me but I guess 11425H works as well?

Thanks so much for your time.
