Current behavior

Columns set by admins in Lists in Jira Work management projects are only available to that user and not shared across to other users.

This is by design: https://support.atlassian.com/jira-work-management/docs/customize-your-list-by-adding-or-removing-fields/

The fields you choose to display in your list will only be visible to you.

Suggestion

For admins, a feature to save column configuration in List view would be a good addition.
