Link dialog box in WYSIWYG editor does not create correct label

I ran this test on XWiki version 7.4.2 running on my Windows laptop which I downloaded straight from the XWiki website (so none of our customizations are there in this version).

When I try to create a link to another wiki page using the link dialog box, the link appears as a long URL. The expected result is that the page URL should display as 'SandboxTestPage' with the page URL as a hyperlink. Please see attached files for illustration.

Additionally, the link dialog box does not appear to have any option to enter the link label.

To summarize, here are the issues with the link dialog box affecting our users:
1) the label of the URL is wrong
2) the dialog box does not have an option for user to enter the label for the link
3) the 'query string' field is non intuitive to a human, I could not understand what it means
4) The embedded link in the dialog box after user selects the page from the page-search window has 'WebHome' displayed as a suffix. The user should not see WebHome for embedding internal wiki link pages as WebHome is a system artifact and not a user-facing page/artifact.

Thanks,
