Ok I figured it out.
You were missing the tvc-guide-title
tag.
tvc-guide-title="Evan's Room"
Because you didn't have all the tags for the fake guide data, it didn't use it and fell back to what you would see if you didn't use those at all.
I'd also suggest using tvg-name
to name the channel too. I was worried the apostrophe at the end of that line was messing it up, but it wasn't. But it seems safe to lean on the tags we support.
