Resource Alert - New Learning Assignment - activity loop not working on 21C

Hi everyone,

I am using the delivered New Learning Assignment with some minor adjustments. The message body text is as follows:

Hello ${assignedToDisplayName},<p>

You are enrolled onto the course ${learningItemTitle}.</p><p>

<% if (learningItemType == 'ORA_COURSE') { %>

<% if (assignmentSubStatus == 'ORA_ASSN_REC_NO_OFFR') { %>

Select an offering

<% } else { %>

Click here to start learning!

The activities of the selected offering are:   

<% } %>

<% } %>

<% if (learningItemType == 'ORA_SPECIALIZATION') { %>

Click here to start learning!

The activities of the specialization are:

<% } %>

<table>

${AlertUtils.loop('completionDetails','<tr><td>${activityTitle}</td><td>${activityDescription}</td></tr>')}

</table>

This unfortunately does not return any values at all. The course has 3 offerings so I am expecting to have those listed. This is the email I am receiving:
