space between images in the mobile version

Hi guys,

Congratulations for the work you carry on.

I’m having problems with the space between "Partners" image in the mobile version of this page: https://stage.wilhelm-waermetechnik.de/

If you scroll down till the "Unsere Partner" you'll see 8 logos.
If I chose the mobile tab in "edit page", the vertical space between logos is ok.

But if I check the page in my mobile browser, the vertical spaces between logos changes, and it looks like a mess.

That I'm doing wrong?

Many thanks in advance.
