Framework7 UI breaks when backbutton click

Recently I built an app (f7 + Cordova) and the UI breaks when I use the back button to return to the home page (index.html)

I don’t know if this question is specific to framework7 but I am building with it so I think this is a good place to start from.

Please any solution, referral or lead?
I have been lost for a week now.

Please if I can equally get optimisation tips F7 and cordova too, it will be geat!
