I am trying to cross seed one of my torrents.

I have downloaded the full torrent from Tracker 1 and it is seeding. I found identical torrent in Tracker 2 and hence I downloaded its .torrent file. But when I try to add it in the client, the client responds: "Torrent is already in download list. Since it is a private torrent, trackers weren't merged."

The client I am using is qbittorrent. I am already cross seeding a few torrents across the same two trackers without any problems. This seems to be the issue with the particular .torrent file.

Can someone guide me how to solve this?
