Using troubleshooting mode running only the plugin and GP, I seem to have narrowed a layout issue down to a conflict between GP and the Post Grid block from “Gutenberg Blocks – Ultimate Addons for Gutenberg” plugin.
Here I detailed the main issue here with vertical margin spacing.

I have tried to narrow the issue using dev tools but have not found luck narrowing down the theme css style in conflict.
I use a child theme, so I tested with just vanilla GP in troubleshooting mode and the issue replicated. When I use a default theme it appears as expected.
Any insight here? I appreciate the assistance.
