Hi, I have no idea, I suggest to check on official Joomla forum, probably you weren't first. Updates are "easy" only on youtube clips. I hope that you upgraded also template, of course, this will not fix your issue, but may help in global appearance.
p.s. you can also check in database if this string "…" can be found, if yes, probably you can easily remove it fron content using smart query in PHPMyAdmin. But first read my first advice.
