It is the sentence "Could not interpret date in [Birth/Death/Marriage] Date (..." which triggers the error. Same for names.
You have to clean up the narrative - the Biography section of the profile. Remove the sentence from the biography. It is only leftover junk from the gedcom download anyway and not really informative once the dates have been inserted in the profile.
This help page is a guide to cleaning up Gedcom-generated biographies. It tells you what can/should be deleted.
Lots of profiles have been updated but trigger the error anyway because of this.
