jira不能将custom field添加到navigator column中

添加了一个自定义的field，但是死活无法让他在navitor中显示为一列，导出excel选择all fields也没有它。但是在navigator column配置界面中明明有这个字段的。
找了jira的文档才发现：

It is possible to add any of the existing custom fields to the navigator column list. When configuring the navigator columns a user can choose any custom field that they have permissions to see. That is, any custom field except those that are project-specific and apply only to a project that the user does not have permissions to browse. Some custom fields, even if selected to be part of the navigator columns, will not appear in the issue navigator for all issues. For example, project-specific custom fields will be shown only if the filter has been restricted to that project only. Issue type custom fields will only appear if the filter has been restricted to that issue type.

我这个custom field的Issue Types被设置成了Bug，所以只有在查看bug issue的时候才会显示这列，如果有其他issue则不显示了。

将Issue Types设置成 any issue type，再把custom field的默认值设为空则搞定。
