Hi there,
Our organization just recently bought Advanced Roadmaps so we are in the initial phase of how to implement and use this product for our teams. Following the documentation we learned that target start and target end date in the plan can be adjusted and once done the header description would change accordingly and show a date lozenge:

We change the Target end to show the Due Date. So we expected that the Due Date would show up instead of Target end. with the lozenge. Unfortunately nothing changes:

What are we doing wrong?
Thank you for your assistance in advance.
Rik
