S10E issues

[carom36]

I have a Samsung 10E and when it last updated, I cannot send photos in a text message to other phones in my office. 

I can send photos through text message to all other contacts.

I i go into contacts in the text message icon, when I scroll down, there are blue dots beside the names of the conacts in my office.

Does anyone know of how to fix this?
