The rows of the live table from the Attachments tab in the Page Index aren't ordered no matter what column we sort by

Steps to reproduce:

1. Click on the Drawer
2. Click on Page Index
3. Click on the Attachments tab
4. Click on each column from the livetable to order it alphabetically (Filename, Page, Space, Author) or by date (Date)

Expected results: The rows are ordered alphabetically or by date as required.

Actual results: The order seems to be random, no mater what column we sort by
