Lifetime not on YouTube TV but appears in my filtered guide?

The Lifetime network famously isn't offered on YouTube TV, but for some reason when I look at my filtered Channels DVR guide, it shows up on channel 6046. I also have DirecTV, which is where I suspect it's coming from, but why is it displaying when I set my webUI channel guide to only show YouTube TV?

It is also not listed when I click on the "126 channels" link mentioned under YouTube TV in the Sources section:

Not a big deal but it's confusing and I'd like to understand the logic behind this, or know if it's a bug.

This is a bug. Technically in the backend there is only one "TVE" guide database, so showing then separately in the drop down is not working as expected.

OK, that makes sense, thanks for explaining.
