Collection variable for notification emails - not working under Nintex for Office 365?

I'm in a unique situation - I am a site owner on two separate Sharepoint instances - one is Sharepoint on prem, the other is Online.  I am using Nintex 2013 on prem and Nintex for Office 365 for SPO.


In my on prem instance (Nintex 2013), I have a few workflows that query a list for names, dumps them in a collection variable, and sends them an email.  No sweat.


The collection variable looks like this:




And emails are sent to this variable value just fine.


In Nintex for Office 365, for some reason, this doesn't work.


Here's what I have.  List #1 with a "Subscribers" column (People&Groups), containing names.


List #2  with a list workflow that contains a "Query List" action.  The Query List action is querying List #1 for the "Subscribers" column and collecting the values in a collection variable.  Under "Columns to Select" I've chosen "Subscribers" and under "With Property" I've chosen "Work email".


The resulting collection variable in Nintex for SPO looks like this:




The workflow can't send to this, and of course I'm getting this error:
