[BUG]Error when using the plugin PlotSquared

[FnTlv]

Describe the bug
I get an error when I use the setup command to generate a plot world, but the plot world is generated normally!

To Reproduce
Creating plot worlds with p setup

Expected behavior
Reporting an error shouldn't happen, so far there is no effect other than reporting an error, is this error something that can be ignored?
