Sorry for the delayed response here, we thank you for bringing this to our attention.
These kind of equivalence issues are common, unfortunately. When artists with similar names (as is the case here) lack enough rich metadata content to trigger disambiguation they are often erroneously identified as the same person.
We’ll take a look at how this information is reflected on our metadata providers’ side and see what we can do. Please understand that we can’t make any promises regarding a timeline for corrections when coordinating with our metadata providers. Thanks
