Generating a Ruined Portal via a Structure Block will never replace any Obsidian with Crying Obsidian. I've generated 5 of every type of ruined portal, and none of a single Crying Obsidian.

Manually Generated Ruined Portals don't spawn with Crying Obsidian

Structure blocks only load the template file, unmodified, generation and jigsaw blocks (and /place structure) will load full structure, with proccessors changing blocks.
Not a bug.
