cubase / korg pa4x program change not working

Hi guys

I want to record some new pa4x style using cubase 9 pro
I know everything about record new style
and program change signal was work fine before some day
but today there’s no program change signal when i choose a new drum kit for all midi channel 9 / 10 / 11 , Etc.

The program change signal works fine when i create midi channel 1 or 2 or 3 for upper1 / upper2 / upper3 but not for channel 9/10/11 Etc.

I made 2 korg MIDI user setting one for upper1 and one for styles and I have not corrected anything but i don’t know why my keboard does not send any program change signal for channel 9 /10 /11 /12 /13 … am I missing something ?
