Do Egg Moves on non-Egg Pokemon set off flags for WiFi battling?

[FEG]

I edited a few Pokemon I'd caught in the wild for online battling, but a couple of them were causing problems. I checked later and realized that some of the moves I'd stuck on them were egg moves, and these Pokemon had been caught in the wild. Is that what raised the red flag, or is there something else I probably did wrong?

egg moves must be on hatched pokemon.

Figured that was it. Can't believe I made that kind of mistake, but I guess that's what happens when you don't fact check. Thanks.
