Components Issue (formerly Global Blocks)

Hello, in the old Global Blocks, you could see a visible I.D. number. Where do you find this I.D. using the new components?

I created (a few years ago) global blocks to display on my site on certain pages. I updated my site to the new X pro theme a few weeks ago. Shortly thereafter, I noticed that my global blocks were showing fine in the preview but wrong on the published page. I attached a screenshot showing the editor (where everything is correct) and a screenshot on the published page where it shows black/none of the formatting is correct.

What could be the issue?
