G12 Finisher Pieces on Hero Finn, Hero Poe & Rose

Hi,

i am still farming those three and i am wondering which G12 Finisher pieces they need.
At swgoh.gg it says:
Hero Poe needs Power Cell Injector (Ionic)
Hero Finn needs Power Cell Injector (Fusion)
Rose needs Power Cell Injector (Plasma)

But all three show the same Gear 12 Finisher Material needed: 50x Injector Cell, which is only needed for the Plasma Power Cell Injector?!

Additionally CG wrote that the Pack description for Hero Finn is wrong and it should say Fusion instead of Plasma...

Could anyone please clarify that they need the gear pieces that are shown in the packs and at swgoh.gg? I dont want to farm unnecessary pieces.
