Parameters - "path" not working

I'm getting a validation error stating that the "in" property for a parameter can only be "Cookie, Header, or Query". Based on the documentation I thought "path" should also be an option. On occasion, the document will validate and not show any errors, but after additional changes, the incorrect validation errors will show again.

Here is a link to the document in question:
