Sleeping in a bed always resets the player's spawn point to the world spawn point

While playing a new survival world i made in snapshot 19w12b (the latest snapshot) i was killed and when i respawned i got the message "your home bed was missing or obstructed" my bed is not on slabs and has more than 2 blocks of air above it, the bed was a double bed so i tried removing one, waiting till night, and sleeping in it again, when i woke up i jumped off a cliff and died, and i still respawned at the original spawnpoint ive tried multiple different things and im now sure that its a problem with the game. I live close to the original spawnpoint so its not really a problem but its a little annoying. Please fix this as soon as possible
