Not sure without seeing the .rsd file, but it looks like you have placed that header and paragraph into the same container as the last sentence on your page. Maybe that has been made a 'symbol', which means that if you change one, you change them all. But I would need the project file to know for sure.

Yes you have added the div holding the h3 & the paragraph to the same div as the 3 images above it, which is a symbol as Inger says if you add something to an element that is a symbol it will be added to the pages that also have that symbol

To delete from the other pages
open a page select the div with the h3 & paragraph, move over to the "Elements" tab then across to the "symbols" tab

there you will see an icon that looks like a chain link which will be highlighted

click on that icon so it is no longer highlighted,

go to the div on the page with the h3 & paragraph you can now delete it from that page

repeat for all other pages

Oh and just as an aside,, you really should consider limiting the width of the paragraph to something like 1200 pixels at the higher end of the viewports, because on larger devices it stretches the full width of the screen, which isn;t a good idea, as people find it difficult to scan words at such long widths

Thanks. Seems simpler if I just add a container (?) below the symbols one. I just tried adding a row below there, and it added a column. So I clicked the tab and set it to row, right?

This is all so confusing to me.

Above "What's Included" on the Home page, doesn't appear to be in rows, so when I limit the rows below it to 1200, it looks weird.

Have you updated your test site with those changes? If you want us to say something, we need to see what is looking weird, and in what way.

you shouldn't change the column to row
if you set a fixed width you should remember to set the l & r margins to "auto"

Sorry Inger - just uploaded the latest.

Lucky I saved yesterday's copy before trying this - it's a real mess now.

I think we can safely agree on that.

As far as I can see without the source file, the page limitation has to be set on some entity inside the one you have limited.

Mellisa put the row column whatever you set to 1200px before back to how it was (probably width=none)& set the PARAGRAH to 1200px as I said before
