Problem with portfolio grid

I edited my site with Elementor and I have a problem with portfolio grid. http://prntscr.com/k3mfag Grid Style is set up to Cards. In this preview, everything is ok, but on a live version [ redundant link removed ] there are no these paddings http://prntscr.com/k3mgii. What’s the problem here?
