So I've noticed that some Pokemon I encounter, come up as something I've not caught even though I own them, example;
I've open up my Pokedex to show that I do have Shiny Pidgey's, I actually have two, both female ones. Is this because it's a different gender or is it an error?
Oricorio (PomPom) and Togdemaru do the same thing but I can't confirm if it was because I don't have that gender because I didn't check (I'll come back and edit this post if I find another one)
