Unexpected space at the end of summary on mobile

Hello!

I have some pages with a summary of products but there's an unexpected space at the end of the summary on mobile and I can't find how to get rid of it or why it is there. Appears on some pages but not all:

https://www.rustique.uk/antique-plates

Same page structure but no space:

https://www.rustique.uk/antique-chargers-platters

I use css to force a two columns display on mobile.

Thanks for the help!

Paul

Solved, it was a matter of removing gutters between rows on fluid engine, should have looked into it instead of going straight to css!
