Am I doing something wrong? On cross-seeding, rechecking, and filepaths

[yommish]

I am trying to cross-seed between tracker A and tracker B but checking torrent B seems to fail if I modify the filepath of the payload at all (via renaming within Content view) which is necessary in many cases to accommodate the files as I've renamed and structured them originally through Torrent A.

Example:

Torrent A initially might look like this in content view:

(root)
└── File.mkv

I want File.mkv to live inside ParentFolder so I rename File.mkv to ParentFolder/File.mkv. and see the change reflected in qBitTorrent:

(root)
└── ParentFolder
    └── File.mkv

and in the filesystem:

Downloads/
└── ParentFolder/
   └── File.mkv

Cool.

But when setting up Torrent B to seed, it seems unable to check successfully in any case where I have changed the filepath.

Setting Torrent B to expect...

(root)
└── ParentFolder
    └── File.mkv

...which should be exactly what exists, doesn't result in successful checks for some reason.
In order to cross-seed I have had to make the existing files conform to whatever Torrent B expects my default.

Any ideas what is wrong?
