Minecraft claimed beds?

I just wanted to know for a moment why my villagers do not mate. They have potatoes to eat, there are some "valid doors", can farm their own food, there are enough "unclaimed beds" (as far as I understand a bed in which I do not sleep).

What am I doing wrong? Can someone help me please?

Wait a night near them, which version do you play

@MaxChemieNoob,

I play the version 1.14.4. Actually, I've already figured out how to make them multiply, just put beds in the open. ^^

But while we're at it, would you happen to know what that is, then could you possibly help me?

@MaxChemieNoob,

I beg your pardon but is there anything else?

I'm so sorry I'm not a pro.

@MaxChemieNoob,

ok I can't blame you, but I hope you understand that there's neither an award nor a thank you. Do you understand that?
