The album Paleolitico XTC by the group Star Park is incorrectly listed as a release by the band XTC. This is not the case on All Music or Tidal (where it showed up for me in a Roon Search of the band XTC.)
Looking into this a bit, it looks like XTC & Star Park are more or less the same band. This release appears to be a re-release of Star Park content under the XTC name.
There’s a bit more information here:
The best option currently is a manual edit to the artist in Roon if you’d like it to appear as Star Park.
