Everything comes out as calculation processor.

Apparently the CreatePlus mod has been abandoned as seen here, however it also looks like there's a fix that hasn't been included in the release as seen here, but it has to be applied to each world, as far as I can tell.

And even that fix is bugged.

Here's a fixed fix. It can be dropped in the world/datapacks folder and restart the server (theoretically the /reload command should work also, but it can cause automatic server scripts to think it's hung and restart). Again, I don't know if this can somehow be included in the modpack, but it does, at least fix the problem.
