Issues with Sliders

I’ve followed the documentation for the creation of sliders, however, the slider appears to not display a background and also doesn’t show numbered tabs to switch between them.

See my screenshot here: https://i.imgur.com/0CE83kh.png
It is also missing the bottom row as seen here: https://i.imgur.com/Kx0flTB.png

EDIT: It appears to not be working in Chrome. Any chance for a fix?

EDIT2: Confirmed working in both Firefox and Edge. This is NOT working in Chrome or Internet Explorer. Please release a fix for these browsers. I’d appreciate it very much.

EDIT3: Weird, it seems to be working in all browsers now. Perhaps it was some weird caching issue I was having.
