Yes - this is a multi year problem that I have attempted to solve every year through support.

It looks to be a user interface issue with white space and formatting issues. 

No matter how the form is edited it changes the line breaks and spacing and I've ran into it for at least 4 years. The previous years I've been able to work with it and eventually get a mass mail out with the proper coding but this year seems to be impossible. It keeps smashing the formatting into a single paragraph no matter what is done (Saving to all clients) e-mailing etc. When you go to edit the format block, it expands the line breaks to the correct "look" but then when saving, it smashes it back. 

Looks to be a program fault and I'm surprised that I can't search here to find others with the same problem.
