Spawnchunks size set to 11 fails to execute

[Lokemol]

So, what happens in this error, is that, once you've SetDefault 0 spawnchunks size, when you try to set it to 11 again, it will give an error, not able to execute that command, the solution that was given to me by altrisi, was to remove the SetDefaul from the Carpet.conf, that seemed to fix it, but as of now, if you setdefault 0, it will sometimes not allow you to go back to 11, from in-game

Can you please try running the following commands in order and post the resulting log output?

carpet superSecretSetting true
carpet spawnChunksSize 11

I encountered a similar issue. For me, this issue seems to only happen when changing between zero and nonzero spawnChunksSize while in close proximity to the world spawn. If I'm far away from spawn chunks, /carpet spawnChunksSize runs successfully.

I ran the commands James103 suggested. Here's my output:
