Its actually completely understandable.
If the wallpaper was the same colour as your notification icons you wouldnt be able to see anything.
its quite cool that they put the transparent feature in there for their wallpapers.
Mebbe a later update will give you the option by asking if you want transparent notification bar ... or the other option is to find a decent developer web site where people are ingenious and helpful and will do this for you .... oh hang on ....... look at the URL!
