What Have I Done to Automation Editing?

Hi Guys, using Cubase 8.0.35.

I have existing volume automation on a track. I must have changed some setting because when I try to manually add automation nodes with the pencil tool, I found it was erasing most of the existing automation on that track. Playing with stuff in the automation panel, I’ve reduced the “Reduction Level” but my automation point editing is still not acting right. When I click to add a node, the node moves slightly from where it was placed and most of the time I get two nodes every time I click. Any idea how to get it back the way it was?

HI,

Could you send a screenshot of your Automation Panel, please? And could you send a screenshot, how the automation track looks like before and after the click?
