See if you have a "Entry Page URL (c26)" dimension instead. If so, use that.
In AA, Pages is not synonymous with Page URL. In particular, from the "(c26)" postfix, I can tell that your page URLs are being tracked to a custom variable, "prop26". So that is an implementation that is not out-of-the-box from AA. Pages are normally tracked with the "pageName" variable.
Now, when you breakdown your Page URL (c26) variable by Entry Page, you have to consider a user journey through your site. It could be something like this:
(enter site) homepage --> page B --> page C --> register --> page X --> page Y
In the screenshot of your report table, you're reporting the page URL of that "register" page. But in this visit, "homepage" was the entry page, i.e. the first page that the user viewed in this visit. As a result, AA is reports that "homepage" was an entry page for the page URL "register".
