template does not show right

Hi,
I made a page (deep dive d’luxe) which I copied. The copied page I changed with different content (pictures and text) but the layout is still the same. And so far, there is no problem. From this new version of the copied page, I made a template. This template I added in another page where the content belongs. And then the problems start because the template looks different on a mobile.

It shows different colors and fonts on the mobile version. It looks fine on the website. It does not look the same on a mobile. Background colours are gone in several sections, background pictures are gone, font colours are changed, the buttons have a different color, and the testimonials are displayed in another color.

Can you help me to solve this problem?

Thank you, Anouk
