Ubuntu 25.04 control buttons not showing up

[rootlinux2]

I’ve noticed a couple of problems when using the Sweet theme on Ubuntu 25.04:

Some application windows do not show the window control buttons (minimize, maximize, close).
LibreOffice does not fully apply the Sweet theme — parts of the UI still use default styling.

The Libre Office does not get the full theme

I'm using Evolve Core, but I did tried with Tweaks
I noticed it is related to the gtk4, I leave it unasigned and the controls show up; then I applied the GTK4 and the buttons disapear again

I'm using the latest version of the Sweet-Dark-v40
