Automatially merging trackers causes obscure error

[secretmango]

qBittorrent & operating system versions

qBittorrent: v5.1.4 64bit
Qt: 6.10.1
Libtorrent: 2.0.11.0
Boost: 1.87.0
OpenSSL: 3.6.0
zlib: 1.3.1

What is the problem?

When enabling automatic merging of manually added torrents, an error occurs.

Automatic merging avoids needing to click a dialog, which is a very complicated UI when opening many popup windows (as only the dialog at the very top is clickable)

Steps to reproduce

1. In settings, go to downloads
2. enable "merge trackers to existing torrent"
3. disable "ask for merging trackers"

Now on every SUCCESSFUL merge, an error occurs

Couldn't add torrent 'magnet:?xt=XXXXX', reason: Trackers are merged from new source. 

Instead, it should not output a notification, let alone an error.

Additional context

none

Log(s) & preferences file(s)

none

It seems that the reason is misleading many. Can the reason be changed to “Detected an attempt to add a duplicate torrent.”
