[Plugin: WP-Property – WordPress Powered Real Estate and Property Management] RSS feed is malformed.

So I am having serious issues with the feed.
First… the one provided by WP property does not work. It displays basic info but no URL to get to the actual post.
I ran the feed through feed validator
https://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fwww.cofe.com.mx%2Ffeed%3Fpost_type%3Dproperty

and I get this
This feed does not validate.
line 23, column 8: link must be a full and valid URL: (10 occurrences) [help]
<link></link>

Amongst other problems… any ideas??
