Back Up Email (Club 867)

In FTH 3, when an email was sent to any club email addresses, it would send the email to both the Primary email and back up email (was called secondary email in FTH 3) if that member had a secondary one set up.  One user who relied on this is reporting that she is not getting emails to the back up email (member name is Lorna Boyle).  In FTH 3 emails and any replies went to both the main email and the secondary email.   I set up a back up email to test and observed that it only sends to the Primary email.  Has this functionality changed or removed, since the field name is now back up and serves a different purpose?  I looked in the documentation but did not find anything.
Thanks
