Help with Metronome Routing Issue

Hi all,

Problem:
I opened an old project in C10.5. The old metronome routing is still in effect but my studio has changed and this routing is no longer valid. I can’t deselect the old routing the old way using the click column in the audio connections output tab because it doesn’t exist in 10.5 I also can’t deselect it the new way in the metronome audio click outputs drop down because I can’t scroll the drop down list (which is a known issue). I have a hybrid studio and I use many outputs. BTW: I already installed 10.5.1 and this did not help.

Question:
Is there a way to edit a preference, xml, etc file to manualy remove the unwanted metronome routing?

Thanks for your help
