Sampler track 'Channel visibility configuration' oversight

Simple bug in Cubase Pro 9 on Windows 10.

The visibility state of the new Sampler track does not seem to save with the channel visibility configuration. Looks like it might have just been accidently left out. It doesn’t matter if you filter it out and save a channel visibility configuration or keep it. It does not respond to any channel visibility configuration regardless.
