Some of those look like they are from Theme Components. I believe you can scroll sideways.

There’s a gradient to hint that you can scroll horizontally:
It’s the same in our profile’s navigation menu, and it’s not visible enough

Hmm you should also get an arrow along with this that will scroll… perhaps there’s a theme interfering with the styles? do you see the arrow in safe mode?

ah right, we hide the arrow on touch devices… the idea being it’s a lot easier to scroll horizontally, but perhaps we should include it there too

Maybe we just hide on narrower screen devices, where we’re more used to scrolling horizontally?
Or, we could reverse the logic – instead of hiding on touch devices (the OP screenshot looks like a touch-enabled laptop), we display it if a fine pointer is available.
