Carriage returns in group messages ("Message Group" feature) are being replaced with the text letters "rn".

1 - I sent a message direct through uddeim and it worked fine. I think it is something that has to be added on groupjive method that calls uddeim api to clean this string.

2 - I tried to change the default editor for this feature to html and wysiwyg and none of them seem to work on the front-end - always showing plain text editor with the text "rn" replacing the carriage return.

Which one is that - I see 10 options on the login module, but none say CB-core (see attached). The documentation doesn't seem to indicate which one is "core" either.
