@roni-fialkow Hi Roni, thank you very much for the reply.
As you said, the problem was that the Item height was set to px value, I switched it to Auto. 
Something else unexpectedly appeared when I changed the height value on all breakpoints. Now the margins between the items are abnormally huge, although the margin value is set to 10 px. Would you know what could be the reason for this be?
Thank you once again for your detailed response.
Have a good day,
Hana
