The artist Karkara is tagged Kakara on Roon library

I just saw that on Roon, the artist Karkara is called Kakara. But the real name of the band is Karkara (and it is correctly named on Tidal for example), which is a problem to find it from Roon. I made a manual change for my library, but the name remains wrong in the database for other users.
What is the procedure for reporting an artist name problem?
Thanks in advance, Robin
