This happened to me in old worlds on the actual 1.18 update when I upgraded my 4 year old creative world to 1.18, how can this be fixed and why does it say Working As Intended?
I think this happens because a shucker is considered an entity, this might be Working As Intended

I have just reviewed he issue after the release of 1.19.0 and the issue has been resolved.
