UCC and UIS , The character does not respond when clicking attack button

hi, I have a problem with UCC and UIS. I plan to make a demo, similar to the demo you provided in the integration of UCC and UIS. When using UCC [Item ability]-[equip Unequip]-[auto equip]-[Everything], the character can attack normally. When I choose to equip it from the inventory by the item action panel (Equip) in UIS ( UCC [auto equip]-[Nothing]) , the weapon is equipped, but the character does not respond when I clicking attack button,without any error or warning.

I find that the [item ability]-[use(Slot 0)] is not activated when I clicking attack button. I think maybe somewhere is set wrong , but I haven’t found it after searching for a long time. The item set manager is activated, and there should be no problem with the item.

Could you help me to fix this problem? Which options in the component may cause this problem?
