Cant find paramater to automate (Sylenth/Cubase)

I have a lead created in Slyenth but when I go the automation section in Cubase 6 there is no where to automate the filter on the Sylenth. There is automation parameters for volume etc. but I cant seem to automate the controls on the Sylenth.

Any ideas as to whats going on here???

Then you can open all the sylenth parameters.
