Moving projects to another drive displays "Repair" in UE4 Launcher

I moved the example projects that I downloaded from the Marketplace to another drive to save hard disk space and the UE4 Launcher displays “Repair” next to the project names. My computer has a 256GB SSD for operating system and programs, and 2TB HDD for downloaded files and data files. I moved the example projects after running them. I don’t want to move the example projects back to the SSD. How can I fix this problem?
