When you select one of them, are both selected? (I.e., they are “just” visual duplicates). It probably goes away temporarily when you restart the Roon server.
I also notice that these are VA albums. Does the duplication start (or get worse) when you scroll to VA in My Albums or past VA and then back? This looks like an issue that occurred in the past, then was apparently gone, but was recently reported to happen again by @DDPS and myself, with the recent posts starting here:
@DDPS wrote that it corrected itself without rebooting. I can’t say because I did reboot for other reasons (and it does not happen now but might again).
