CoreELEC 19.4-Matrix_rc2 Discussion

Sorry if this is not the right place but I can’t get an answer after 5 days to my question here;
When I press a key on my RC, CE takes multiple same actions, for exemple if I move in a list, it will jump to 5-9 items further.
I’d guess there is a place where one can set de delay between actions. Where?
Thanks
