Journeys - Combined task notification

Summary:

We are trying to create a custom template for combined task notification for Journeys. We are using Notify owner and performer of tasks initiated seeded template that is pulling through notifications for worker and performer as expected but the links in details are taking to users to checklist tasks rather than to Journeys task.

When we are creating the custom template copying the seeded template , the tokens are not pulling through the task list. They are working when we use the seeded one.

Please can anyone advise on how to get the details link point to Journey tasks when the custom template is used?
