villagers don't sleep and work

I moved bell from another village to the village I wanted.
And I re-replaced the bell a few times.
After that, villagers were unable to enter their houses.
villagers don't sleep and work.
At night, it seems to me that they don't try to get into the house.
And even if the bell is replaced with another bell, villagers are still not working and sleeping.
I tried placing two bells, but villagers are still not working and sleeping.
Strangely enough, the effect appears when I replace the bell.
And it looks to me like the residents are chatting near the bell.
(I made roads right in front of the door.)
(I created the village myself. Residents were also brought in from another villages.)
Why did this happen? And what is the solution?

I can't attaching my world file.(.mcworld files is 80mb)
