Villagers struggle to get in their bed

Villagers struggle to get to their bed when night comes. I believe it's because they have some sort of hitbox with the villagers that are already sleeping.

File is too big so I have to attach link to video. https://photos.app.goo.gl/3x1aDyrGXNjedBcK9

Edit: what is unclear in my report??? sigh.

Step 1. Get villager (bobert)

Step 2. Get bed for bobert

Step 3. Repeat 20 times or more (beds nust be attached to each other and not make a line)

Step 4. /time set midnight

Step 5. Watch the 20 boberts struggle to ger in their bed.

THEYRE SUPPOSED TO JUST WALK ON THE BEDS TO GET TO THEIR BED, BUT NO
