unable to change langugae using the indicator in kubuntu 20.04

[daggs <daggs@xxxxxxx>]

Greetings,

I've encountered a strange issue with kde on ubuntu 20.04.
when I set two layout and try to switch, it is stuck in en no matter the order.
setting specific shortcuts with the meta key didn't worked, left shift+left alt doesn't work either.
ctrl+alt+k works but only lists en.

any ideas what can be the issue?

Thanks.
