Timestamps disappearing on comments

Sometimes, when I upvote a comment in a sentence's discussion forum, the timestamps on many of the comments disappear. It doesn't happen all the time, but often enough to be annoying when I am trying to see when someone posted a certain question/response. I am using Duolingo in Google Chrome.

I've had the exact same problem, also using Chrome on Windows 7.

    This has happened to me in a similar way: i changed my username, and it always showed my old username still but when i upvoted stuff it changed to my new username.

    What happens if you refresh the page after you upvote the posts? Nothing?

    So far, the glitch has only appeared on the sentence discussions while I am in the middle of a lesson, so refreshing the page means losing my progress.
