A project imported from AD has "Missing files" (Old library files now joined in an IntLib, the original AD PcbDoc etc).
How can I remove the reference to these files from the project? The tooltips (see included pictures) are both impossible to follow, sadly, as clicking on the Project, there is no such option, and clicking on the files shows no menu whatsoever.
EDIT: Typo (PcbPrj -> PcbDoc)
