editor page no longer mirrors live page

Wordpress 7.0.2
Wordpress was updated recently since a new Jetpack subscription messed a lot of things up. I don’t know where to findGenerate Press 3.6.0 – there’s a note saying an update is available. Generate Blocks 2.3.0 Generate Premium 2.5.6 It is all posts. It is only off on the editor’s preview. I’m sending you an old example of one already published side by side, which doesn’t show how bad the photo placement can get when I’m working with several small shots instead of the larger 2 in the example. It does look like type size is the issue, but I’ve never had a way to set the editor’s type or anything else any differently than the live page. The one I’m working on has lots of smaller shots that require really precise placement of text and spacers and really shows you the difference, but it has no published page I can show you, only the editor’s preview. Do you want that one side by side? (As you can see, I can’t quite get them entirely exposed when side by side.)

In case this is relevant, the screen shot I’m sending you shows two other problems that happened at the same time, presumably with the WP update; 1) The photo you see in the post background is supposed to be continuous across the page, including behind the content area, but the content background, which is set to a dark green color for other areas, has lost its transparent command for the content background only, which used to override the dark green color. 2) See the 2 white bars below the content? They didn’t used to be there and I’ve tried everything setting I could think of to disable it and nothing does anything. They take up valuable ‘real estate’.
