I am trying to apply stylesheet that I downloaded in qml format from GitHub of Ordnance Survey https://github.com/OrdnanceSurvey/OS-VectorMap-District-stylesheets/tree/master/GML%20stylesheets
Master Map looks fine in the default styling but when I apply the style that I downloaded makes the Map disappear. What could be the reason to make it disappear into QGIS.
Same happens with SLD stylesheet
Below is the screenshot of the attributes of the QML stylesheet
