Issue Summary

Hiding the Epic Link field seems to interfere with the parent-child relationships in custom hierarchy levels above the Epic.

Steps to Reproduce

1. Set up two new hierarchy levels above the Epic, such as Program Epic and Custom Epic, following the guidelines in Configuring initiatives and other hierarchy levels. .
2. Create a new field configuration, e.g., "Test Field Configuration," and hide the Epic Link field in this configuration.
3. Create a new field configuration scheme, e.g., "Test Field Configuration Scheme."Associate it with the issue types Program Epic and Custom Epic, using "Test Field Configuration" as the field configuration.
4. Go to your Project settings > Fields > Actions > Use a different scheme, and select "Test Field Configuration Scheme."
5. In this project, create a new issue of type Program Epic, e.g., "Program Epic 1."
6. Create a new issue of type Custom Epic, e.g.,"Custom Epic 1," and set the parent link to "Program Epic 1" during creation.
7. In "Custom Epic 1," the parent link is correctly set to "Program Epic 1."
8. However, in "Program Epic 1," no child issues are displayed.

Expected Results

"Custom Epic 1" should be linked to and displayed as a child issue under "Program Epic 1."

Actual Results

No child issues are linked or displayed under "Program Epic 1."

Workaround

Remove the Epic Link field from the hidden fields in the field configuration.
