When I sort by "status" or "last seen" in group management with a site that has 50+ endpoints, the sorting only applies on a page-by-page basis. For instance, when I sort by status, an endpoint on the second page that "needs attention" will not show up at the top of the first page, but instead will show up at the top of the second page. The sorting applies to each individual page of 50 and doesn't re-sort the whole group of endpoints and re-order them.

Everyone's been begging for this since at least 2013 - I counted about 8 feature requests here
. The current behavior is intended: no one knows why.
The only thing I can advise is get familiar with the API and write your own tools or interface to perform routine management tasks. We've had to do a ton of custom scripting to manage Webroot since we moved to it a year ago.
