[Q] MMS sending with (no subject) before every text topic

I recently upgraded from an iPhone 4 to the Nexus 5 and i'm loving it! when I try to group text over MMS with my friends, who all have iphones, they receive the text just fine over MMS and I can reply, view, all the normal stuff, but every text they get from me start with (no subject) in bold over the normal message. Anyone had this issue before?
anyone know how to fix it?
I have already tried a plethora of messaging apps and made sure my MMS settings are correct and can't seem to find any way to remove the (no message) from the messages.

Any help at all would be appreciated!
