Answer 1

The documentation says:

The content of the file should always start with the Kivy header, where version must be replaced with the Kivy language version you’re using. For now, use 1.0:

#:kivy 1.0

Note that the documentation says should. Not having #:kivy at the start of your kv is not an error. The software that you are using is incorrectly calling that an error. But to satisfy that software, just copy the line from the documentation as the first line of your kv file.
