Activation Condition issues

ive been trying to recreate an effect i saw in the MidiQOL video with Baileywiki, which is doing an effect when hitting an undead or fiend creature. in the video the MIDIQOL had an activation condition of this:

["fiend", "undead"].includes('@raceOrType') && @item.attunement !== 1

but when that is input into the activation condition section of the weapon or even using the same weapon from the compendium (mace of disruption), it doesnt apply that extra feature or effect to just undead and fiend, it does it for all hits on all creature types. any help?
