When I make a  numbered list within a note in a drawing, stop numbering for a line or two, then start numbering again, right-click the second group of numbered lines and click "Restart numbering", the lines in the second group are all numbered '1'. See image:

This is forcing me to create separate notes for each numbered list in my drawings. Any drawing that was created in 2014 is broken like this when opened with 2015. Also new drawings created in 2015 have the same issue.

Am I doing something wrong? Is there some feature I'm missing somewhere? Or is this a bug?
