Duplicate Status, Project and Priority in Admin section when XObject on page with localization variants

[KebabRonin]

There are some situations when the various lists in Task Manager Pro in the Admin section break.

XObjects on pages with localization variants

Steps to reproduce (steps are the same for project and status):
2. Add a SeverityClass XObject with a name like Test Outside on a page with existing localization pages (like the Sandbox page, which has 15 versions for various languages)
3. Save the page
4. Check the Task Manager Pro Admin section

Expected result:
The Test Outside severity appears only once in the severity list.
Actual result:
The Test Outside severity appears multiple times, once for each localization version.

This is more an issue from liveTable macro (which is used to generate the Admin section table).

The issue is only visible if the user explicitly modifies the page objects through the wiki, and not through the Admin section as intended.
