MISSING CHANNEL?

I’m using an Hauppauge Quad HD. When I Channel scan in Plex, one channel is missing. 44.1 The channel is available in the Hauppauge windows app, and in fact is one of my strongest channels. Plex sees 44.2, but acts as if 44.1 doesn’t exist. Thoughts?

Ok, so even stranger- recordings scheduled for this channel record, but it won’t let me watch live. Has anyone had anything similar?
