Bing Webmaster Tools and index.php

I am not sure if this my problem or if it is Bing Webmaster Tools.

I have pretty urls enabled and I pasted the code given when switching on pretty urls in the backend, into my .htaccess file.

I have checked my sitemap.xml and there no “index.php” anywhere.

When I inspect my uls in Bing Webmaster Tools dashboard sometimes I get the report shown below saying that the page cannot be index because of a redirect

When I click the box to inspect the redirection at the bottom of the page shown in above screenshot, then I get this from Webmaster Tools

I must admit that I really don’t understand Webmaster Tools, Google search console is bad enough, but for me Webmaster Tools is worse.

At the bottom of the above image there is an error message in red referring
to ` tag

When I turned on pretty urls in the Concrete backend , the box Add a <meta rel="canonical" href="..."> tag to the site pages. was automatically ticked.

Should the <meta rel="canonical" href="..."> tag be included ?? if so why does Bing Webmaster complain about it ??
