Spinning Wheel After Contacts Name in Messages App

I have a problem where when I want to send a text message or iMessage and I start to type in a contacts name; the auto-populate shows me the name, I click the persons name, but then a little spinning circle appears next to the persons name and I can’t send the message.

furthermore, if I do this when composing a group message, the contacts with the spinning circle are removed from the message and only some of the contacts I selected are actually in the to field of the message. The contacts that had a spinning circle are removed automatically And aren’t included in the group message
