Would you please use https://snipboard.io/ to provide a screenshot of what you’re seeing?
There are no duplicate choices in the default export screen. The duplicates you see are likely due to additional plugin or theme post types. Even though the labels appear to be duplicates, I suspect the input field’s value attributes are all different. The values would indicate what post types are actually chosen if you pick that particular input field. To see the value attributes, right click a round radio select option, then select “Inspect”.

Alt + Print Scr works on my Ubuntu box, but does not paste here.
So I put the screenshot here (Page/Post duplicates marked): https://www.care4tulbagh.org.za/export-duplications.png
The first pages/posts items with pop-ups are the true WP posts/pages for export. The “duplicates” are likely custom post types added by theme or plugins. They are possibly not meant to be user facing, so the labels were never set to be anything meaningful.
If you’re curious about what they might actually be, go ahead and export one of them. You can view the export file in a text editor and see what sort of content is within each post. I expect them to not be regular post/page content but something else. If by chance I’m wrong and you still get regular posts/pages, it’s due to some quirk of a plugin and the export quality could be suspect.
