Neep help with basic Item modifications

So tinkering around with modding and making items. started with modifying a few ingame items already, and one specifically had a special ability. found the special ability in records>skills>itemskills>legendary, and made a few adjustments. Made sure the item was still pointing to that itemskill.

I go into the game, and the items special ability is still the basic template, without my changes. is there something else I’m missing that I need to do in order for the game to recognize the new ability numbers?

For reference, I was adjusting the Game item and skill itself, I wasn’t in my own mod at the time. So the base game item is the same, the special ability has modified stats. but those stats don’t reflect in the game.
