Video of the bug

This is a video showing how the notifications still appear on the wrong display.
Comment 2 Álvaro M. 2025-02-23 18:12:41 UTC 
Update: This happens only when both displays have a [default] panel. The notification goes to the display with the last created panel, no matter if the notification was configured to go to the primary display or not.

In other words, a workaround is to remove the panel from the primary display, save, and then create a new one in that same primary display. This way, KDE displays the notifications in the last created panel: the primary one.

The same happens on X11 as well on Plasma 6.
