Relume Starter Plan: Sitemap Page Visibility Issue Explained

Hello, I'm not sure whether this is a bug or user error as I'm new to Relume. I have the Starter plan, but only 4 pages of my sitemap are showing on my wireframe. There are 9 pages on my sitemap, I see them all in the wireframe but with 5 of them blurred out with the message to upgrade to view. I would expect the number of visible/workable ones to be 5 rather than 4, since that's the number of pages allowed on my plan. Am I missing something here? Also wondering if there's a way to select which 5 from my sitemap are translated into wireframe, or whether that's random and I therefore need to delete any extra pages from my sitemap entirely? Thanks
