Keyboard layouts are not being mapped correctly.

Describe the bug

If there are more than two keyboard layouts, every layout starting from the third will have the same shortName as the second.

This is most likely an issue with SDDM.

To Reproduce

Using SDDM with X11:

1. Set the layouts:

setxkbmap -layout "us,br,jp,fr" -variant "altgr-intl,,kana,"

2. Test the theme;
3. Open the language popup;
