I use elvui and jamba together with no issues, a comparison of some settings might help. I have the all the default settings under the dps setup for elvui. I've moved a few frames around but I doubt that would change anything related to chat. In jamba I have the entire team listed and assume team online UNchecked, I've changed the default channel name and password and of course pushed all settings. Every team I have uses the same settings aas I often run with other guildies for boosting and whatnot and this keeps it simple. I can probably post a quick breakdown of every setting and how I currently have it configured if it would help.
