Platform settings not applied for new target

Hi folks, new to Xcodegen. I am trying to add a watchOS app to an existing project. After a lot of setup for the new targets I tried to build and am getting the following errors.

I copied the target files from other targets that were app-extensions in the project. I did build with XcodeGen with the wrong platform and type without thinking to change any of the settings. While trying to debug, a lot of settings for the target file have been removed and I am left with only the necessities, correct type and correct platform. This and the other watch app target are both the exact same besides the name. I have tried changing the platform to tvOS as well and it doesn't change the errors. It refuses to change off of iphoneos in Xcode

name: redacted WatchKit Extension

schemes:
  redacted WatchKit Extension:
    build:
      targets:
        redacted WatchKit Extension:
        - running

targets:
  redacted WatchKit Extension:
    type: watchkit2-extension
    platform: watchOS

    sources:
    - path: .

Thanks for any help.

Start with the shown XcodeGen target configuration and reproduce the generated project using the watchOS platform and watchkit2-extension type. Trace how the target's platform setting is carried into the generated Xcode project, then verify that the generated product type resolves for watchOS instead of iPhoneOS.
