Here is my issue
1. There is a team-managed project, with sprints feature disabled
2. I made a filter on it and created a custom scrum board for it.
project = BI AND (assignee in (123, 124, 125)) ORDER BY Rank ASC
3. Tickets on the scrum board looks fine, but tickets with Epic are not showing on the backlog. Also, the Epic panel on the backlog is showing unlabelled. Epics panel and backlog on the main project do not have this issue.

Things I have tried and didn't work
- Create a custom field for Epic Name and put in some values
