Is there no longer be HD again for 720p?

[zhugelianges]

Hi everyone,
I got an issue.
Usually after I using Youtube requirements upload, as 720p, there would be a 720p*HD sign. Like this,

But then no matter I watch 720p video, or I upload 720p video, the button become this (no HD again for 720p)

Anyone know what happen?
Thanks a lot!!
