MMS In general on Android never functioned properly, even for people who didn't have my contact before I got the phone. It was usually okay in the default messaging app but any 3rd party texting interface would mess up entirely when images or media were sent. I never had any issues like you are describing with group messaging to my knowledge but for that sort of thing I am primarily a groupme user so even if I did it wouldn't affect me.
