Automation emails - Mirror columns not populating?

I am using an automation to send a custom email for a status change. The email template pulls both regular and mirrored columns from my board (all were available as possible columns to choose from for the email). We noticed that a mirrored column (Request ID) doesn’t populate in the email. Monday bug, or am I doing something wrong?

The column in question shows as {pulse.mirror5} in the email template, but appears blank in the actual email. There is definitely data available to pull. Thanks again!
