Bug: Combee doesn't learn Air Cutter

Ight so I was doing a Male Combee solo run as one does and I saw that Combee learns Air Cutter in Platinum and HGSS and I need to replace Gust. However much to my dismay, Combee could not learn AIr Cutter despite learning Ominous Wind which it learns from the same tutors. This was very bad for my run as in my second fight with Zenith, Gust could not OHKO his Volcarona at +1. This means I had to get 2 Ominous Wind boosts which lead to the fight taking 6 hours to win on easy mode with healing items (no x-items tho I am no coward). Please let my precious boy cut the air.
