There are currently 14 different Profile Completeness suggestions. Here's a link to the current list of possible Profile Completeness suggestions (I don't know if videos have been created for any of them):
A WikiTree member requests Profile Completeness suggestions for profiles for which they manage by adding the category [[Category:Suggestions_-_Include_Profile_Completeness]] to their own profile
If the individual whom you are helping didn't request the Profile Completeness suggestions, I'd suggest that they just ignore those particular suggestions, and let the PM that requested the Profile Completeness suggestions work through them. If they have a question about a specific profile with a Profile Completeness suggestion, I'd suggest that they contact the Profile Manager(s) of that profile.
