Yeah, thats why its a glitch!
I finally found a way to do this, and try giving your egg pokemon an item then save the file, the next time you load, it will have it UNCHECKED on the met tab!
oh and don't worry about the glitch, its AWESOME! before i tried to send the usual egg files from PokeGTS to my game, it works but the link trade thing is missing, now it tricks the system into thinking this egg was gotten from a link trade, pretty cool dontcha think?
