Villagers constantly showing breed particles, then overbreeding!

Put the summary of the bug you're having here

What I expected to happen was...:
Villagers should stop breeding once they run out of beds.

What actually happened was...:
Villagers constantly breeding, then overbreeding.

Steps to Reproduce:

In 1.14 (stable version), the villagers had hit the population limit. I think there were around 20 beds and 20 villagers. Also, we completed a couple of raids, but I don't think the bug showed up yet. But after some amount of time, they suddenly all just showed breeding particles, and sometimes the "lose reputation" particles would show up as well. But no baby villagers were spawned.

I updated to 1.14.1 Pre-snapshot 1 today. Now the particles reappeared, but now baby villagers also appeared in huge numbers. This is despite the fact that there are no where near enough beds close to the village. There are now probably 50 or so villagers, but still only around 20 beds in the area. We have our own beds in our base, but only at most 6 other beds on the server.

The save file has been attached. If someone can help me troubleshoot how I can fix this issue, that would be great!

(I also have a backup of the server from before I updated to 1.14.1 Pre-snapshot 1, if that helps)
