Titlebar is not disapparing when maximized

Hi guys
I am in Manjaro KDE plasma. I have enabled a widget called active window controller. I have setup all customization and i disabled titlebar for maximized window show that I have extra space and the controlors are on top panel. It runs okay first but when i restart it stays the same. It automatically unckeck the box and when I maximize window it doesn’t hide titlebar.
I checked the file called kwinrc in .config folder. It also resets automaticall When I restart.
What might be the solution for this??

Are you using Latte Dock? It has a setting that interferes:

You can also try adding this line in ~/.config/kwinrc. Log out and log back in to see the effect:
