When using the slideshow with thumbnail images (see picture) and changing these settings for desktop, it maintains the desktop settings on mobile.

So, when I've changed to mobile settings, and made the thumbnail images smaller, then it stays that way for desktop.

For some reason it does not style them separately.
For now I'm cloning the slideshow and changing the settings for each to show on mobile and one on desktop.
Thank you.
