Anyone install Corsa Extremes and have an issue with the Valves closing in Sport/Track/V mode?

Valves also no longer open on cold start.

Tried to perform the Valve Relearn and no luck.

Anyone have any idea what the fix could be?

Scanner shows the position at 10% then goes to 80-90%.
Valve state shows out of range/ unrecognized state…
