Switching between keyboard layouts in Arch Linux breaks other key bindings

Question

I am new to Arch and have this problem:

I want to have two keyboard layouts (en and bg) and switch between them using the alt + shift command. So I did everything as it is written here , and everything works. I have two layouts and I switch between them using alt + shift.

But ... when I try to move the window to another desktop (for example, ctrl + alt + shift), it does not work, it only changes the keyboard layout. And this is not the desired effect. It should only move my window to another desktop without changing the layout.

The same thing happens if I use ctrl + shift. Then I can not insert the terminal using ctrl + shift + v. Only switches the keyboard layout ...

I am using this line:

setxkbmap -option grp:alt_shift_toggle us,bg 

I use LXDE if that matters.
