Track Preset Not Saving Instrument

Hello All,
May be I am missing something:
I have a Midi track with a Vst instrument assigned and a patch loaded. I save it as a track preset.
Now, when I try to load it again it doesn’t load the instrument and in the inspector it says “Missing: Input 1” where the name of the plugin should be. I have to manually load the vst and choose the patch. Not much point in such a preset.
Also it insists on saving it as a Midi Track preset without adding the instrument…
The presets that came with Cubase load just fine (9.0.10)
I can save an VST instrument preset but I would like to do it from the tracks instead.

Any ideas?
Thanks
Javier
