It's not a bug because that's the expected behaviour. You could consider it a missing feature if you need to make changes there. Open a feature request: https://redmine.pfsense.org/

This is the first time I've seen anyone ask about it in 10 years though so it's clearly not a huge problem.

You could just patch the file to create the config with the values you need then carry that as a custom patch in the patches package.

@johnpoz
Yes sir they said that I can disable that

It is a huge burden off my shoulders

@shooters running into the same problem. Were you able to hunt down a solution?
