Shield doesn’t register as up for a second

(This has been happening for a while but since it hasn’t been fixed I’m making this report now.)
Whenever I try to raise my shield it seems like it takes around a second for it to register as up because if I’m fighting a skeleton, I still get hit by the arrow even when I have the shield up. This is really annoying because it makes fighting skeletons extremely hard because normally I could alternate between shielding and hitting with my sword without getting shot but now I can’t.
