Custom admin menu section name for Jira plugin

Hi everyone,

I am trying to change the section name within jira admin menu.

For the confluence the web-section item worked fine:

<web-section key="my-custom-admin-section" ... location="system.admin" ...>
   ...
   <label key="My Custom name for the section">
</web-section>
<web-item... section="system.admin/my-custom-admin-section" ...>
...
</web-item>

But the same tags in the atlassian-plugin.xml for Jira don’t work. The section is named OTHER.
What can be the reason for that?

Thanks,
Stas
