Summary Block Images Not Formatting Correctly

I have a summary block that pulls in blog pages, but the images suddenly are not formatting correctly. It's a carousel format where the images should be 1x1 square and focused on the center of the image. However, it's now showing up as if the image is not cropped and aligned to the 1x1 square in the top left corner (so most of image is unrecognizable). Also, on mobile, the carousel is showing up as a group of 5 columns, when it used to be more responsive so the content doesn't look so crowded.

When testing on incognito Chrome window, it loads incorrectly formatted, but then switches after about 10 seconds to the correct formatting. The same happens on a regular mobile Chrome browser (not incognito), where it loads incorrectly and then I navigate away from the app or page, then go back to the mobile Chrome browser and it looks normal again.

Does anyone know of some sort of bug with this summary block? I *think* it might be related to a cache issue but I can't have all of our users clear their cache for it to work correctly...

Thanks!

I don't believe that this is a cache error. Have you got anything in Custom CSS?

The highlighted properties are being overridden and causing the images to be too big, when I add !important to them in the dev console the images correct themselves.

Glad that's working correctly now!
