Villagers not going to bed.

So I just started a new 1.14 minecraft world and settled in a village. I made a couple of houses for the villagers to breed and be able to hold more villagers. At night however, the villagers don't end up going to sleep and instead just walk around either at the doorway, opening and shutting the doors repeatedly or just going outside and dying. Its getting really annoying because my villagers are dying. Please fix this.
