Love this app, PDF handling

A truly fantastic app. Unfortunately, all PDF readers on iOS are displaying watermarks that are print-only. Since it is very strange that all readers do this, its hard to know if Adobes problem or Apples problem or the apps problem. It is extremely annoying and problematic. Please fix this! Please also make the background behind pages black when the page doesnt fill the whole screen.
