Is the json error correct?

All of the monument data under the data directory gives me a JSON linter error.
Is it correct to use this as is?
Should I fix it and use it?

Hi, this doesn't affect the plugin's functionality.

I checked because the plugin wouldn't start unless I fixed the linter errors.
If I manually remove all invalid commas, the plugin errors go away and it starts.

If I delete and relocate the data directory and configuration files and then reload the plugin (resetting it to its full default state), I get the following error:

Failed to call hook 'OnServerInitialized' on plugin 'DynamicMonuments v1.2.5' (FormatException: Input string was not in a correct format.)
