Dark Mode Toggle does not change Windows Dark Mode, Just App Mode

[lavavex]

Describe the bug
When enabling the "dark theme" It only applies to apps, and not to windows.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Tweaks'
2. Click on 'Enable' under Dark Mode
3. See error

Expected behavior
This should set App AND System to Dark mode, and not just Apps
