I evolved my Nincada a little early, trained it a few levels and now i wanted to edit its moveset by using the playerdex
but for some reason you can't teach Nincada moves to a Ninjask
today I also updated Delcatty (early evo as well), but didn't have any problems there
i made a screenshot of the movesets from Nincada, Ninjask and the moveset the playerdex is giving:
PS. Bug Bite is missing on the PWO wikia, but as you can see it is available ingame
