G2G: Error 897: Error in template parameters [closed]

Question

A fair number of error messages are showing up with error message too long: Numbered parameter: 2 () {{Ancestry Sharing| when using WikiTree Sourcer.  Another member asked me about why they were appearing as errors in a profile.  I got the exact same source created by WikiTree Sourcer when I tried.  I then looked at my weekly "Suggestions" and I also have six of my own, all added in the last few week.  FamilySearch sources seem to be fine.

Thank you.  That did not show up in the possible "previous" questions...
