I'm having a few problems with legit Pokémon being shown as illegal

[Schrix]

I'm trying to migrate my Pokémon bank to home but I wanted to double check the legality of my Pokémon before doing it so as not to run the risk of being banned for hacked mons. So I transferred my Pokémon from Bank over to Moon and put that save through PKhex and I'm not really understanding why some of my Pokémon are being flagged as illegal. Especially the ones I legitimately caught in-game. 

 

The strangest part for me is the fact that I had no problem having the Pokémon stored in the Bank in the first place without any errors or anything.

 

A bunch of Pokémon I legitimately caught in Pokémon Yellow such as Clefable, Machoke and others are being flagged with "Invalid: Move [number] PP is above the amount allowed"

I'm assuming it's because of changes to the moves Nintendo did between generations but I'm just not sure what to do. Do I just leave them as is and they'll be fine or should I try and "fix" the invalid PP?

 

There's also other times where, getting the same message about PP, I go to check the (again, 100% legitimately caught in-game) Pokémon's moves and the move that's giving the problem shows as having 255 PP or something ludicrous like that. I'm not even sure how that happens.

For example, my Pokémon Yellow caught Mewtwo is showing its attacks as

 

Swift - 205pp

Psychic - 10pp

Barrier - 109pp

Recover - 10pp

 

I'm assuming changing that back to a legal setting would fix that? But how does that happen in the first place? It also seems to only be happening with Gen 1 Pokémon

Is it some kind of glitch with PKHex or something?

I am having the same problem, is there any way to use the batch editior to reset all the pp's to there correct values?
