Sitemap does not work

Web Scraper version: 0.4.2

{"_id":"strobl","startUrl":["https://cs.strobl.cz/"],"selectors":[{"id":"data_xml","type":"SelectorSitemapXmlLink","parentSelectors":["_root"],"sitemapXmlMinimumPriority":0.1,"sitemapXmlUrlRegex":"","sitemapXmlUrls":["https://www.strobl.cz/sitemap.xml"]},{"id":"nazev","type":"SelectorText","parentSelectors":["data_xml"],"selector":"h1.detail-heading","multiple":false,"regex":"","delay":0}]}

For two weeks, scratching the web with sitemaps doesn't work for me. Loading a Sitemap does not return any data. More sites, more computers - the result is still the same.
