Editing Direct Offline presets in Cubase Pro 13

I have some presets for Direct Offline Processing and have them in the Favorites box on Bank 1. I’d like to be able to edit these presets. Is there a place I can find these or do I have to create new presets and delete the old one, which I’d prefer not to do. I can’t edit them without having a track selected and it starts processing as soon as I select the preset. Is there a way to open the preset to examine it or can I only see it if it’s processing? Any help is appreciated.
