The Geni Consistency Checker will report "Suffix in name" on any profile that has multiple words in the first name, last name, or birth surname fields where at least one word is recognized as a valid suffix. For example, "Smith Junior" will trigger this inconsistency but the name "Junior" by itself will not.
This inconsistency is always considered a Warning
Auto-fix: There is no auto-fix for this inconsistency. If in fact the name contains a suffix, you should edit the profile to move it to the Suffix field.
