Similar situation with my shiny Seviper not being able to learn Sucker Punch with the Mirror Herb thing. It only could learn it through Move tutor in Platinum, I had one and now it lost it, I don't mind that much but still absolutely retarded.
Also, I checked and Breloom learned Spore at lvl 1 in BDSP but in SV it indeed only learns it as Shroomish.
