Siri suggestions with custom type

I would like to use Siri suggestions along with a custom input parameter type. The custom type works perfectly within the shortcuts interface, but the suggestion is never carried through.

This is particularly egregious by using the "Key Parameter" as the parameter gets its own icon.

Has anyone gotten that combination to work correctly?

Thanks,
Adam
