CoreElec grabs duplicate keys

Hi there,
New install, Odroid N2, Coreelec v19.4, universal remote control SONY.
I followed the how-to to setup my URC with meson-ir , working but some key have rebounds.
For example, running ir-keytable with 1 press less than half second I get:

CoreELEC:~ # ir-keytable -p NEC,RC-5,RC-6,JVC,SONY -t
Protocols changed to rc-5 jvc sony nec rc-6
Testing events. Please, press CTRL-C to abort.

In CE/Kody, some keys are fine but other repeat the action few times.
Where in the remote setting, can I find a way to avoid this behaviour?
Thanks

Is there someone to tell me where I can find Remote Control settings to set the delay before repeat?
Thanks

Sorry, I guess like me there are many of us who just copy the configuration file remote.conf of our infrared remote control in the COREELEC partition of our boot flash memory so that everything works as it should.
