Yes, for me due to copy and pasting the first tracker device and altering the settings for the second device, the problem occurred i tried many ways but no solution.
The Following Solution worked for me :
As of 19-11-2024 you need to delete all the tracker devices(by taking screenshots if they are involved as Function or Event for other device , i mean screenshot to refer while reusing them with same settings in future) and restart UEFN and Fortnite and even Epic Launcher (for fresh start) .But , remember never copy and pasting the first tracker device and altering the settings for the second device in future until epic fix this . Hope Epic Games Fixes this soon.
Thank You.
