I have some strange titles when I get comment notifications for my nomination on [SO] there stands something like "6|rekire" in the title. I guess that comes from the 6 in the URL https://stackoverflow.com/election/6
I'm pretty sure that this does not happen often however this is a small bug :-)
Edit: The "dublicated" question Missing links to responses to comments on nomination posts is about links in the web. I'm talking about the app. So that question is related, but not a dublicate at all.
