Why aren't my Minecraft villagers sleeping?

I built a Villager Breeder, designed by ImpulseSV. I had brought two villagers to me from a village and multiplied them and then took the babies for the breeder. When the breeder wasn't quite finished, I had the problem that the villagers slept, but didn't wake up in the middle on the fence post, but on the beds.

When the breeder finished, they just didn't want to sleep anymore. I checked the structure several times, as far as I know, I didn't build the beds, or so. I also broke the original beds and all the beds in the area.

Do you know the problem and do you know what could help?

Correct version? The villager mechanics have been changed several times.

Impulse's Farm is for 1.15. You probably play in 1.16. That changed how villagers sleep / where they wake up.

Here is a fix for 1.16:

Probably wrong version, think that's the problem. Because who is still playing in 1.15

I play more often in 1.12 with cool mods.

The problem is that they don't even sleep. I've tried it and unfortunately it still doesn't work.
