MS and program change receive

Sorry if I missed this, but is there a known bug with the MS and program change receiving?

I am using the DN as the master and it works great sending program changes to other gear, but with the samples I have to manually change the program change back and forth on the midi screen every time I want it to change. It works if manually changed but not when saved with a pattern and then changing pattern (like my Korg and others do).

Thanks in advance!
