Preview vs live version problem

At the first look on my mobile phone (settings to dektop mode) it seems to work, i will take a look in the morning if it works on my laptop.

If something like this happends, is there anything i can do to change it back?
We would like to publisch thr page to our customers around the start of januari and options poping that shound be available is a big issue…

Kind regards,
Kristof
