Hello Muscar. According to the screenshot you provided the links are html pages, from which you get to the direct link where the content is stored, that is why when you download, for example,
Folx downloads the html page instead of the .rar file which is only reachable by the direct link insider this html page.
Thus, the only option is to get to these direct links manually and download needed content from the direct links one by one. Or, as an option, Folx is a convenient torrent client and you may check such tv series in search and download them much faster in several clicks.
