Short description of error
When I try to copy and paste an object it's not making it single user, it's pasting as if I had duplicated it (same as Shift + D)
The single user toggle also isn't working.
Exact steps for others to reproduce the error
Copy and paste an object, make it Single User (Object Data)
Do this again. It won't become single user.
I have to do it two times for it to take effect. Sometimes I have to toggle off the Object Data which was previously selected, click on it again, try to make it single user then click on it again.
[Based on the default startup or an attached .blend file (as simple as possible)]
