Custom CSS elements

Hi,

currently I’m testing Pro version of your plugin.
And I have a problem wit Custom CSS file.
I created it and added there:

#printfriendly #pf-src{
display:none;
}
#printfriendly #pf-title{
display:none;
}

#printfriendly #pf-header-img{
display:none;
}

On a preview, there’s visible only a picture to print. But when I press “Print” there are also a date, an image’s title (On the top), and an URL of a page (on the bottom) added.
I checked all your support materials but couldn’t find the solution to that problem.
Are you able to help me with that problem?
