Hello, I'd suspect these 'ghost entries' correspond to some text you have entered recently. It is one of Zim's powers to turn any words looking like page addresses (starting with a plus, or containing a colon) into links which you can immediately click to create the page you have 'mentioned'. And as long as you don't click on it, these pages appear greyed out in the index.
As I very often write about computer names and ports, delimited by colon, I got used to the habit to mark the link (you recognize it immediately by its blue color) and press Ctrl+9 for "clear all formatting". At the next save (or autosave) the ghost entry goes away.
