qBittorrent official forums

Up until a few days ago upon completion of a download, I would see 'Seeding'. If I then 'paused' the seeding I would see Completed.  And unless I deleted the Completed entries they stayed there forever.  This is how it's been for years. Then about two days ago all my 'Completed' disappeared. Now when I download a torrent I get a pop up saying file has been download but I do not see seeding and I do not see Completed. The entry just disappears.  What can I do to restore my previous setup? 

Please note that I am being prompted to upgrade but the last time I upgraded all my pending downloads, completed, etc.  disappeared and all I got was a blank  screen.  As well, what I have has been working like a charm until this blip.

Any help is appreciated in advance.

Have you hidden the left side of qBitTorrent's main window where there's checkboxes for:
Status
Categories
Tags
Trackers

...Under the Status one, select All and the torrents hopefully show up again.

If that doesn't work, qBitTorrent may have been set to delete the torrents on completion...in which case there's not much you can do except re-download them all!
