Customers keep watching static channel; no lot traits

I opened a small business today using the "bar" preset. The customers came to watch TV, and they turned on the static channel. Edith showed up (half-glitching to look like a spider demon), and my customers had bladder failures and/or passed out. However, this lot does not have any lot traits, which means the static channel shouldn't be available. My sim, the business owner, cannot choose to watch the static channel unless a customer is actively watching it.

This also isn't a case of Edith showing up of her own free will, because only YA and older can enter the business.

A screenshot of how no lot traits or challenges are enabled, but there are urine puddles on the floor, sims have passed out, and most sims are stinky.

The same lot in live mode. Edith shows up behind my sim, looking like a spider demon due to how her body has glitched.

Screenshots were taken on two different in-game days, but the only thing I changed about the lot from Thursday to Friday is buying a barbecue.

This save is my never-modded save, aka the save I use while I wait for it to be safe to re-enable mods and cc. I can be 100% certain that mods are not causing this issue. My game is updated to the latest patch.

P.S. If there is more than one TV on the lot, and different sims watch the static channel on different televisions, is there supposed to be more than one Edith?

There are currently two of Edith. One has begun to throw a tantrum. Neither is a spider demon right now.
