Admin → Members → Member Bulk Load → Upload History lists sessions without downloading every member snapshot, so the tab opens instead of hanging until Mongo times out.
Choosing a session then loads that snapshot only, so Members uploaded and Member actions still show the people from that load.
Manage History keeps a member count per session without fetching the snapshots, and the date preset list now includes Last 2 years, Last 3 years and Last 5 years between Last 1 year and All sessions.
The date preset dropdown sits above the slider so the left edge and focus ring are no longer clipped by the admin frame.
Manage History and the diagnostics upload-session list have sortable headings, a newest-first default and sort settings that stay in the page URL.
In diagnostics, click a session delete action again to confirm it, or use Cancel to keep the session.
