I’m having a similar issue, except my problem is on mobile. The thumbnail images were showing up super tiny (literally dots) with lots of space between them. After a LOT of trial and error I was finally able to solve the issue on desktop using the following settings:
Navigation: Yes
Infinite Loop Defalut : No
Navigation Button Background Color: #ffffff
Navigation Icon Color: #000000
AutoPlay: No
Thumbnails To Show: 1
Space Between Thumbnails: -475
Thumbnails Half Effect for First and Last Item
Add the % too Display : 10
The problem on mobile now is that in portrait mode, the gallery is only showing a single tiny thumbnail, whereas in landscape mode, it works perfectly. I’m assuming it has something to do with my Thumbnails to show setting (1) but that was the only way to get the gallery looking normal on desktop.
