Keyboard layout appears twice in upper panel

I am using Ubuntu 20.04 with mate desktop, and trying to add a new keyboard layout.

This is how I do it:
System -> Preferences -> Hardware -> Keyboard

Then I added another language:

In the upper panel I see the layout twice>

Any idea how to fix it?

>Solution :

You have to do the following:

1. Visit Language Support (gnome-language-selector) application to set Keyboard input method system to None

   

2. Do right mouse click on blue EN (IBus Preferences interface) on the top MATE Panel, then uncheck Show icon on system tray

   

   and enjoy.
