I have submitted a correction to our metadata provider for this credit. I’ll be sure to keep you updated here once I’ve heard back from them.
For future reference, you can choose the Submit Corrections link on the AllMusic page for the album and your correction will be directly sent to the provider.
Our metadata provider has let us know that they have corrected this today. Please give this about a week to be reflected within Roon. Once you see the change on your end please mark this post as the solution.
