Dipthong Problem Doves v DØves

I’m having a problem in getting Roon to differentiate between Doves and DØves with regard to metadata, specifically in “Appearances” on the DØves artist page. When I initially added DØves to my library the artists and albums were wrongly amalgamated but I was able to resolve that problem by ensuring that my watched folders in Windows had the correct Scandinavian spelling of Ø for DØves to distinguish it from Doves.

After fixing that I noticed that Doves albums were still showing up in Appearances (and only there) on the DØves page, as shown in the bottom image.

How can I get Roon to recognise that Doves appearances do not belong on the DØves page?
