Multiverse Core issue

Hello. I was making a minecraft server with Aternos service, when at a certain point I decide to put Multiverse Core. To continue with the development of the server, I need to remove mobs and animals. However, by doing this, multiverse core did not enable worlds. When I tried to enable them it gave error. Please help me, because I don't know how to do it.

Server version: 1.19.2

Software: Arclight (There wasn't a chat for mods/plugins)

Attached are the demonstration images

P. S.

It won't let me upload the images

Here are the pictures

Ok

Don't pay attention to the fact that Geyser doesn't work

Oh, so what I should do?

The HUB world shouldn't exist because the world should be called "world".
The thing is, this is a test server, which I created by downloading and reloading only my main server's world. Apparently it seems that the name of the world has changed because he decided, and I don't know how. I hope I explained it well.

I tried deleting the Multiverse Core "worlds" file, but when it was automatically recreated, it started looking for worlds with the name "HUB". Now I'm sending the log.

The problem is that the creator hasn't a support service

Thanks for your support. Have a nice day
