Keep inventory not working unless toggled w cheats

i’ve made about 3 different worlds to test out the new automatic keep inventory + achievements for just simply peaceful as i build a house to start, and i died then spawned back with nothing at all. if i turn cheats on it’ll take away my achievements but the new feature doesn’t take them away. couldn’t find an exact same issue in the lists so decided to make another.. if i do it again ill try to post a screenshot of it.
