while hold attack enable, is doing nothing

i toggle it in gui, the hold use tweak do function, but the hold attack tweak doesnt have any effect,

and I found out that enable in tweak toggles tab doesnt have any effect, but set tweak hotkey works

did you toggle it with hotkey?

The Hold Attack and Hold Use tweaks should be enabled with a hotkey combination that includes the attack or use key, respectively. Otherwise the action will not properly activate/deactivate, unless you then separately click once after toggling the tweak. I can probably fix this though...
