Sleep Timer doesn't work

It seems to work for Video but not for Audio.

There is also other issues :

• When you first set the Sleep Timer, the 1 should not be in orange, but white, like others numbers.
• After set a sleep timer, you may want to stop or modify this settings. But, first, if you try to click again on the Sleep Timer, nothing happens, but the Text disappears. If you clik again, then yes you can modify Sleep Timer.
• Moreover, there is no more Reset button... but we have to thing about this point with others Advanced Options issues...
