When I try to print a custom field that is a Cascading Select in an email template, I get extra information that makes it not usable. For example, it prints when I use: $issue.getCustomFieldValue("customfield_11406")

{null=Client Services, 1=Client Pickup BH}

I really just want the "Client Services" and "Client Pickup BH" parts. How do I do that?

I have tried all the solutions on answers.atlassian.com, but none work.
