QNAP version 1.7 (build 667)
I ripped an album, then realised I had the wrong album artist and ripped it again. Going into Roon to check it had identified the album correctly, I realise I now had all the tracks duplicated under the same album - so deleted the erroneous 12 duplicate tracks (on the QNAP). But Roon still showed 24 listed under the album, despite rescanning and restarting Roon. So I deleted the album folder and files entirely (on the QNAP). But Roon still lists the album and, when I try to delete it in Roon, it can’t find any of the tracks so refuses to delete. I tried putting the album back on the QNAP (with the 12 correct tracks), but when I try to delete on Roon it still lists 24 tracks and says it can’t find any of them.
I behaves the same when trying with my PC and with my ipad so assume the problem is with the core rather than remote.
How do I get rid of this album and start again?
