Odroid c4 remote controller

Hi,

I have Odroid C2/C4 running 9.2.2 version of Coreelec. I’m using HK Ir controller (https://www.hardkernel.com/shop/ir-remote-controller/). I’ve read some guides how to configure it an I’ve configured both systems the same way for IR controller. The problem is that the controller is not working smoothly on C4 - sometimes I have to press buttons several times to get it working. On C2 it is working smoothly without any problems or delays.
Do you have any idea what could be the issue there?

Thanks
