MCX8000 effect buttons don't work since serato update

I’m not sure if this is a Denon or a Serato theme. But i have the issue that the effect knobs on both sides don’t work properly anymore. that means: in the beginning it was like this: effect off button light off, when i push the effect on the button light was on. NOW: the button light flashes only for a short moment during i push it and goes directly off when i go away. AND: sometimes the effect is on and i have to push the button again to switch it off sometimes NOT - ■■■ ?

down anybody knows this issue ? i cannot use the effects these days I’m not sure since when i have this issue because in the last weeks i didn’t use the effects but now i will have some electronic gigs and i need it to work.
