'How can I stop Xcode 13 from displaying multiple compiler errors or warnings for each that actually occurs

I have already looked at the following:

Each question's accepted answer is just an explanation for why. I tried the only proposed solution I could find (from schillace), but it isn't working for me. I changed the setting, rebuilt the project, restarted Xcode, rebuilt the project again, and it still isn't working.

Schillace's Solution:
Go to Project -> Edit Project Settings, and check the "Build Active Architecture Only" button in the Architectures section. Duplicate Errors Solution attempt

Every error and warning gets duplicated, not just the one in the image I provided. How can I get these duplicate errors and warnings to go away?
