The crossbow is not firing

I load the cross bow with arrows but it fires air. It says loaded with an arrow but when i fire it nothing happens.

I load the crossbow and it just normally fires an arrow.

I loaded it but it fires nothing.

1. Get a crossbow
2.Hold right click and wait till it s drawn back.
3. Fire

I believe this is only a bug for me because on other worlds it fine but mine is a slight laggy.
