Yes, hand edit this time.
I've spent a fair amount of time in the past trying to figure out the issue with the ID blank lines. I've even submitted some questions on the EA forums about that and haven't gotten a good response. It seems to be an internal EA issue not directly associated with the rtf template scripting.
I have noticed a loose correlation between the newer the version of the SysML Requirement element being used and the more lines shown. For example, SysML 1.3 requirements have 5 lines, and older versions have 1, 2, etc. lines.
