Automation issues

Hi everyone
Would greatly appreciate if any Halion experts might be able to help please.
I keep having persistent issues with the mapping of automation to the Filter(s) in Halion. It doesn’t seem to behave in any way like the other zones which all seem pretty stable and recall-able.
In this instance/example in the image, I’m trying to map Filter cutoff, resonance and distortion inside FM zone inside ‘Layer FM’. The automation is named Program.1.Filter.Cutoff (instead of Layer.FM.Filter.Cutoff or ‘FM Zone.Filter.Cutoff’). The peculiar behaviour is that the parameters affect each other (as if there was a conflict) but there is no conflict (I’m 99.5% sure).
Can anyone suggest anything please?
Many thanks
Jon
