I’m lost with resizing

I turned on the image resize detection and I see in my blog is says all the images are oversized. It shows as an example the images are 1246X418 (in yellow) and then X 418X262 (Green)

I went to an image in the blog post and selected edit then set the scale to 418X 262, the screen came back and said the image was saved and I can verify the preview said the same.

I selected the set as featured, updated, cleared the cache, and did the preload in WP rocket.

I reloaded the page and it says the same exact thing 1246X418 the size did not change even though WP said it was scaled.

What am I missing? I think I have found a long-time issue with my blog page and google page speed and want to fix this. Strangely my pages are all fine, they show in green, and google page speed loves those pages, it is just the blog and all posts.

I would like to be able to make sure I can do what I need before buying this plugin. Can you point me in the right direction as to what I need to do ti fix this problem?
