Hi Jeff it is likely that they visited you late in the 24 hr window and early in the new 24 hr window. Hence, you may see it twice.
Unfortunately, the game doesn't use a 24-hour window in a way that makes sense (resetting every day at the same time). It starts ticking 24 hours from whenever you visited that town.
I consistently get the wrong names on my films. For example I watch my roommate visit me, and the buildings he clicks show up in my town with a different name.
I think you are experiencing this wrong name bug, with the same wrong name showing up multiple times.
Sometimes, the game randomly shuts down on me while I'm doing my friend visits. If I go back to whatever town I was in, it usually shows me that I still have actions to complete when I know I was finished or almost done. Also, whatever buildings I tapped are no longer available, and I have to find new ones to tap. I've always wondered how this shows up to my neighbor. Maybe this is what you're seeing.

I thought they fixed that bug quite a while ago?
Oh that's very possible. I haven't tried it in ages!

Yep, that bug is long gone. It was fun while it lasted. I made a point of keeping most of my graffiti-able buildings near each other for that purpose.
