in one of my most used creative worlds i have seemed to have lost the ability to remove entities without a sword or bow.

(ex. if i spawn a mob and try to hit it the mob will not take any damage unless i hit it with a sword. if i place a painting and tap again to remove it, the painting will not despawn unless I use a sword. if i place a boat or mincart i can only destroy it with a sword.)

this is only in that one world...my others are fine. so can anyone tell me how to fix this?
