Roon on default settings and for identified albums doesn’t use your file tags, all the metadata is form third-party metadata services. Did you change Roon’s import settings and if so how (what settings are you using right now)? See also:
thanks, I messed around quite a bit with this; there we 2 number 8 tracks while one of those was actually track 5 on the album. In the end what brought a solution (now I thus know) was unidentyfing and re-identifying the album. This is sorted therefore.
