Simon Preston Haydn Mass set incorrectly recognised by Roon

Roon appears to have problems with some classical sets and incorrectly slots albums as being no 2 in the set. I reported on this before with another set except this time the tracks were incorrectly labelled and Roon insisted it was disk 2 when the track timings obviously fitted with disc 5. I tried helping Roon by correcting the header but that made no difference.

So the choice was to edit each track or to laboriously use the down arrows to align the tracks up correctly. I did use the down arrows although editing would have been a lot faster,

However this obsession with albums being No 2 in a larger classical set appears to be a Roon bug.
