I've looked into this - this looks like we'll need to refactor parts of the component, as at the moment we just do name comparison, instead of targeting an actual index in the options provided by the parent component. I'm going to leave this as a open bug, but we'll want to look at this later down the track when we have more time, and we haven't got so many issues waiting for this release.
