there seems to not be a disable button on the effect that was applied on item or am i just simply blind, or is it intentionally so once applied u cant take it off?

Effect fusion is permanent, you can't deactivate it once the effect is fused with an item

also joint textures act kind of funny with the glowy things, they show through the joints when playing with objects on, but in replay they dont show through joint textures for some reason

It's a bug, replay joints were using bodypart effects instead of force item's effect. Will be fixed in release build.
