GNOME - Window buttons not changing to match GTK theme

In GNOME 13.2, for many applications the window buttons like close, minimize etc don’t change to match the ones provided by the GTK theme, so it looks bad and it’s really getting my OCD going. I tried setting it with the “gsettings set org.gnome.desktop.wm.preferences theme” command, and I made sure the theme is in /usr/share/themes but nothing has been working. One thing I noticed is that the folder of my theme I put in there has an x on it, and right click > properties says the contents are unreadable. I haven’t been able to find any up-to-date solutions that might work, anyone have an idea?

UPDATE:

  1. The folder started actually showing up as readable.
  2. I tried the “gsettings set org.gnome.desktop.wm.preferences theme” command with sudo preceding it and got the error message “(process:17162): dconf-WARNING **: failed to commit changes to dconf: Error spawning command line ‘dbus-launch --autolaunch=7a76120bcb8ff82cb8550d3e544e5ee2 --binary-syntax --close-stderr’: Child process exited with code 1”

ANOTHER UPDATE:
So after a lot of weird tweaks, I noticed the GTK theme (flat-plat) appears in the GNOME Tweak Tool under the window theme list. Changing to it there, in the case of applications that did not change their window icons before, shows the correct buttons that should appear, but when I hover them it has the wrong effect- the theme should make them have grey circles under a hover, but when I hover over them now it still uses the whiteish boxes that are part of the Adwaita (default) button’s effects. How can I fix this?
