I saw your posts and wanted to clarify something:
This is indeed not best practice here since as you mentioned ROCK is going out to the network and then referencing itself again which is not a good thing to do.
Mike discusses this behavior a bit as well but you would want to have the first location (Roon Optimized Core Kit Internal Storage) set to “Enabled” and then disable the second InternalStorage path so that it is not referencing the local storage through the network. Once you enable the Internal Storage using the non-network access method your music files should start showing up again.
You can also read more regarding ROCK storage in our ROCK Storage Setup Guide. Hope this clears up things a bit.
Thanks,
