Slick + Mixitup - how to make a filter that works in two lines?

Question

JavaScript

I configured slick to be two lines, similar to jsfiddle , but there was a problem with
Mixitup - due to blocks connected with rows, filtered images are not grouped along the edge of the block. I tried to fiddle with styles for blocks so that they were not located in a line, but nothing came of it. Are there any other solutions?

At random, I found out that when you change the width of the line in which all the slides are nested, they begin to wrap to a new line. However, this is corrected only through the browser console and with more slides, they can get out on the third line.

I tried to divide the slider into three blocks of 8 images, in total there are 2 lines of 4 images in each block, without a slider using float for images, they are pressed against each other regardless of the block, however, when the slider is connected, they fall. I rummaged for clearfix in the properties from slick, I didn’t find anything like that, a mystery.
