Watch face not updating and cannot change from F to C for temperatur

I have just d/l the Facer app on my iPhone for my Misfit Vapor and I can upload watch faces however the dials or info within the face don’t appear to be working. I can get the time and the day however the heart rate, temperature etc are staying the same the whole time like they are just a picture. When I click on the watch face to edit, it’s just comes up with the app version number and to d/l more faces on the phone.
Also the temperature section is in F not C so no use to me. Am I missing something in how to update the watch face so it is accurate??
Thank you
