Old messages on top after transferring from Android to IOS

I've had this problem since transferring to IOS from android, using the "move to IOS" app.

Basically, opening the messages app, I find several years old conversations on top. Saying they were sent right now.

Obviously seems like a bug related to how times are stored. As if IOS can't determine the time they were sent and then sets it to the current time for some reason.

Everything on google just tells me to restart the phone or sync with iCloud and other solutions along those lines, which obviously doesn't solve this problem. Please help, it's very annoying.
