Hello @InspiritusYoga,
I've tracked the issue to your case, and submitted it to the engineers for further review. If and when they have an update, they'll notify you directly. Due to the recency of the issue, they're still collecting info and troubleshooting, so there's no ETA on a fix at this time.
In the meantime, the only workaround would be to copy an existing email from outside of the series into your series for the steps, as those copied templates do show the headers for viewing and editing.
