My smart thermostat & extension kit still shows as needing to be installed within the app???

Hi, I was unable to follow the installation instructions from the app / website for our extension kit as the wiring did not match.
I have installed it following instructions from support but when I look at it within the app both the extension kit and the smart thermostat both just show the Installation instructions link and that alone.
We are using the smart thermostat to control a single room.

If I click on installation instructions it does not see it as already installed.

I have emailed support several times but frustratingly keep getting the same unanswered replies.
