[TYPO3-english] cs_seo extension and suffix in link path.

[Dmitry]

I'm using TYPO3 7.6.x, cs_seo 1.8.6 and realurl 2.1.8. Realurl works with "Enable automatic configuration".
When I try to get sitemap.xml I'm using this link http://mydomain.com/?type=655&tx_csseo_view=pages

My sitemap looks like

<url>
  <loc>http://r1arch.ru/derevo/sitemap.xml</loc>
  <lastmod>2017-02-25</lastmod>
</url> 

Why in absolute link path is suffix "sitemap.xml" And how I can remove it?
