Keyboard Layout Switching Shortcut Does Not Cycle

Hello! I switch languages between English and Farsi a lot. Unfortunately, Manjaro is making that switching difficult. Despite assigning a shortcut—Alt + Shift—when I click the buttons, it does work. But when I click them again, they don’t. I have to manually switch back to the first layout, then the shortcut works, and when it switches to the second layout, I have to go back and manually go back to the first layout…you get the idea.

Is there a fix for this weird problem?
