Isn’t this the problem that Mark A and I found with markdown clickable links yesterday? () in lists automatically triggers quotes around that string.
Briefly, Mark found an answer that worked: we had to substitute {} for () in the list and then .replace("\{","(").replace("\}",")") once the list had been built. (The {} has to be escaped because they are special characters in regex, of course.)
In our case we’d been adding the parentheses in the collect statement, while it looks like yours are already in $Citation, so you’ll have to do an initial transform (would $Citation.replace("\(","{").replace("\)","}") do it in the collect statement so that you’re not disturbing the real contents of $Citation?).

Does that help?
