Query loop posting latest post text under older post headlines

No, I haven’t. Are you saying that the headlines and texts match on your own blog, or that you’re looking at my blog and not seeing the problem?

Here’s what’s still happening on my own blog:

• Visit themonstersknow.com. You’ll see that the latest post is titled “Unspeakable Horror Tactics,” and the text begins, “Sorry for my silence.”
• Scroll down past the fifth post and click on “Older Posts.”
• Now the top post on the page is “Dullahan Tactics.” However, the text beneath it still begins, “Sorry for my silence.” This isn’t the case with the other posts on the page, just the top one.
• Scroll down and click on “Older Posts” again. Now the top post is “Death’s Head and Boneless Tactics,” and again, the text begins, “Sorry for my silence.”
• Click through on the title. The text on the actual post page is correct, beginning, “Hello, hello!”

This is continuing to happen even though I just wrote and posted a new post yesterday. The repeated text on each page was updated with the text of the new post, but the glitch remains.

I’m not sure how or why this worked, but I turned on the “Inherit query from template” setting in the query loop block, and that seems to have cleared the problem up.

I don’t have the Gutenberg plugin.
