[PROBLEM] ARTIST: UNKNOW ARTIST

I'm playing an audio CD. It was displayed as Unknown Album so I
entered the information from Library tab including Artist, Album and
Title as you see in below picture. However, on the bottom of the
player, next to equalizer looking thing, the artist is still displayed
as Unknown Artist? Why is that? I've restarted WMP 10.00.00.3646.
Problem wasn't fixed. Note the red rectangles in the picture.
