LG V10 on AT&T. I have 2 text messages sent to me that never downloaded properly that won't delete...?

They were both sent on Sept 30th, so this is very annoying at this point. There is also 1 sent that the phone says weren't, and I get the same notifications. All 3 involve 1 person.

Anybody know a way to get rid of these, without deleting the entire person's text history?
