This issue seems to be reflected on third party twitter clients like tweet, you can see an example of this issue occurring in tweetdeck too.
Update: This issue has seemed to be disappeared, I took the snapshot at the right time on the twitter web page. Looks like twitter was over capacity some minutes ago, here is another snapshot taken by one of my friend Achal shown below.
