??

The same problem, and it still open question – how to make it work properly?

I have a solution.
In plugin folder find the file wpgis.front.js and find setting verticalSwiping: true, and change it to false
(i have it on 55 line).

Also if you would like to customize your slider you can use settings from this link https://kenwheeler.github.io/slick/ because it uses slick slider inside ??
