Current description under the field:

Log information about these entities will match these entity attribute names (can use a mapped attribute above, or built-in: id, idIndex, email, subjectId, subjectIdentifier, subjectIdentifier0, subjectIdentifier1, subjectIdentifier2, entityAttributeValueCache0, entityAttributeValueCache1, entityAttributeValueCache2, entityAttributeValueCache3 to match grouper or sync representation). Note you should enter two values for the target representation and either the grouper or sync representation

The highlighted text is confusing.

• Why should you enter two values? What happens if you only want one?
• Do you enter two values for the target, and then one from either the grouper or sync representation? Or do you enter two total from any source?
