Full screen background image doesn't go full screen + text size suddenly changed

Dear Enfold Team!

I’ve made a website for a client some time ago and after restoring the site from a backup and updating all plugins and theme the color section background image is not showing correctly anymore. The bottom of the page is a profile picture and this should go all the way out to both sides of the browser as a fullscreen color section background image. It did this when we first built the site.
I’ve tried some trial and error and found that our section right below the upper fullscreen image is the one creating the problem (maybe there is more than just this?). We have a blogpost in the “Aktuellt” color section and this – for some reason – makes the bottom color section not able to show full screen. This worked when I created the site though so how is this possible that it suddenly changes and doesn’t work? The site is oldozjavidi.com

Another thing is that suddenly there is a change in the font size for the “Aktuellt” color section (our blog post) after I edited some pictures in the masonry lower on the page. Why does this happen? The post itself has the right size font: https://oldozjavidi.com/jag-stannar-till-slutet/ and it worked earlier with the correct font size.

Thanks in advance!

All the best,
Toni
