Ingrain/Baton pass in game

[Kbary]

I have 3 problems and would like the moderation team's help with them.

1st - Malamar has a move that I can't teach it in-game, the move "Baton Pass". It's not listed on the Wiki, but it's listed on several other websites and in the Pokédex; Smogon also has this move, but it's not possible to teach it in-game, as shown in the images below.

2nd - The same issue occurs with Bellossom, which also cannot be taught the move Baton Pass.

3rd - The move "Ingrain" is described in the "Roar" move description, which states that if "Ingrain" is active, it should prevent "Roar" from working. However, when tested in-game, this doesn't happen, and the Pokémon switches out. Furthermore, Ingrain is supposed to restore 1/16 of the Pokémon's HP at the end of the turn, but it's not restoring HP.
