having multiple crossbows loaded in the hotbar , firing one of them would make some of them unload for no reason

having multiple crossbows loaded and firing one would make some of them unload, i was in creative mode here is a video (pay attention to the hotbar)

^{p.s sometimes the crossbow doesn't even fire and it gets unloaded without an arrow coming out! , this maybe a tps thing since i had 60ms , but i am not sure}
