How to stop setlist sending midi programme change messages

[deminda]

I am using mainstage with my kronos LS88. I have made COMBI's which uses channel 15 set as EXT2 to send midi programme changes.
My global channel is channel 16. I have added the COMBI to the setlist and each time I change the setlist patches the setlist itself send programme changes. As an example if the setlist box 1 has a COMBI which does not have EXT 2 set up to send programme changes , still the kronos sending a message which change the mainstage patch to 001. If I turn off the global setting to stop sending programme messages, the COMBI is unable to send the message. Is there a way that I could stop the setlist sending midi programme change messages and only use the settings within the combi.
( Mainstage has a setting to select a midi channel to receive programme changes but I use a montage also send midi programme changes. So I cant use one particular only)

Did you try de-selcting the Enable Program Change square radio button on the MIDI Filter 1 Tab in the MIDI filters?
