In my library there is a blank entry. When I click on it, there is a blank page with a Steam logo at the upper left corner and a circle that goes around it, like it is trying to load a game. When I right-click the entry, then select, "manage," there is an option, "remove non-Steam game from your library" but selecting it does nothing. When I right-click the entry, then select, "properties," nothing happens. Any way to remove this entry from my library?
