This update fixes netherite tools not being detected as valid dual wielding items.
I also updated the API, since the off-hand item gets put in the main-hand slot during the duration of the event for plugin compatibility it now swaps them around so you can get both. it's recommended to use the getItemInMainHand and getItemInOffHand in the API rather than getting it from the players inventory as it swaps them correctly and removes the items meta data used to detect if an event was triggered using an off-hand action.
