• [X] The title of this issue accurately describes the bug.

Steps to reproduce

1. Go into the settings menu
2. Open the "Theming" section of the settings ("Current theme" is whats gonna be changing)
3. The default is "System theme" (1/14); switching from it to "Catppuccin Mocha (mauve)" (2/14) and vice-versa seems fine, but a bit laggy.
4. Switch from "Catppuccin Mocha (mauve)" (2/14) to any other theme from the next ones.

Expected behavior

The theme should immidiately switch to the selected one; the number (n/14) should be updated, as well as the theme name in the selection menu.

Actual behavior

Nothing happens after button presses. To apply the theme correctly, you have to exit the theming section, and enter it again.
