I'm not sure how to explain this or what it'd be called, but previously it was behaving this way and recently it changed and I would like to change it back.

I have a ultra wide 49" monitor that I split down the middle. When I open an application, it used to show the application open on the right side of the split and it was easy to keep track of all my applications open. Now, when I drag an application to the left side of the split, it removes it from the taskbar on the right side and goes to the left taskbar, and vice versa when I move the application window to the right side again. What setting would stop this and go back to keeping all open applications on the right split side taskbar? Hope I explained that well enough.

Edited to add:
Nevermind, I found it.

Under Settings > TaskBar > I had to choose "Windows taskbar shows no windows, DisplayFusion shows all windows".
