I think I'm starting to follow this. I now need to buy Xtra StylePak 2 to have everything except the audiophile version?
Previously, I purchased on 2nd Dec 2016
Band-in-a-Box EverythingPAK Upgrade with RealBand (BUER-I)
2017 Bonus 49PAK (49PAK-I)
I purchased on 5th Aug 2016
All Xtra Styles PAK 1 (XSP1-I)
Have I missed anything?

:-)
