I have no appsettings.production.json file in my application (I might have once had it but if so, it was deleted months ago).

In tracking down an unexpected environment property setting I discovered that in my dev slot there’s an appsettings.production.json, with about 40 properties set in it. It appears to be a copy of my appsettings.json from about a month ago.

How does this happen? And how do I get rid of it? The file does not exist in my GitHub. My code is pushed up to Azure by a GitHub Action.
