nStream Shows Different Variations of Album Track Mixes

I have a small problem with the way nStream shows an album ...

I downloaded a 96/24 double "CD" & it came in as a continuous single download with 27 tracks,  these were number 1 thru 14 & 1 thu 13,  consequently are shown in nStream as mixed up dics 1 & disc 2 = 1-01 2-01 3-02 4-02 & it plays each track alternating between disc 1 & disc 2.  I already own & am very familiar with the original CD & its annoying.  

So I have rearranged the tracks from the original single folder to two folders "Disc 1" & "Disc 2"

Problem is,  under the nStream "By Folder" it shows & plays exactly as intended, disc 1 or disc 2

But under "Artist-Album" or "Album-Artist" is shows & plays just as it was downloaded, as a single mixed track album.  In both Windows Explorer & Synology file folder it shows it only I intended in one main folder with sub-folders labeled disc 1 & disc 2.  I've rebooted the Synology & NDX & re-installed nStream & no change

Any ideas ???
