Hello
We try to import the backlog of a project hosted in jira cloud. The project has defined 'Sprint' as a custom field. When we export the backlog we get two csv columns with the header 'Sprint'. That is because a story can be implemented in more than one sprints.
The issue is that when we try to import the backlog through a .net backend, using the Atlassian.SDK nugget package and more specifically the _jiraClient.Fields.GetCustomFieldAsync() method, the custom field sprint has no value.
And the jql is:
project = "project-name-goes-here" AND type in (Story, Bug, Epic) AND resolution is EMPTY AND (Sprint is not EMPTY OR Sprint not in openSprints())

What could be a reason for this?
Thank you very much!
