Gutenberg only - no page builders.
I have a backup, but would like to figure this out -

I'm working on a site and have Columns containing two smaller columns - the one on the left contains a featured image, and the one on the right contains a short description.

Template is for a single item post.

I had it set up so that the image in the left column, remaining in its original aspect, would fill its column horizontally or vertically scale (maintaining aspect ratio) to no more than 75% VH.

This ends up in a Query loop. It's basically a bunch of artwork with descriptions. However, after the update, I'm getting some layout issues that look like the bottom image, with a big gap between the artwork and the text. So, I'm trying to figure out what's causing the gap.

I do have some CSS set up, but I haven't changed this & it's been working for months.

Let me know what other additional info I can add here that might help. Hoping this is a fairly known or easy thing to fix.

Not sure how to troubleshoot this - any suggestions appreciated!

Thank you!
