Hello. I have a question about Add-0ns.
I use BB2018 Pro, Win10.
Since my BB is the basic package, I just thought I would get whatever Add-ons I need as I go.

I recently bought RTs set 58 (Jazz & Pop Waltzes) because I want jazz waltz with even feel.
I simply thought if I buy this set, I would get those seven patterns as shown on the page,

Bass, Acoustic, PopWaltz Ev 085
Bass, Acoustic, PopWaltz Ev 085 (A:simple)
Bass, Acoustic, PopWaltz Ev 085 (B:energetic)
Piano, Acoustic, Rhythm PopWaltz Ev 085
Piano, Acoustic, Rhythm PopWaltz Ev 085 (A:simple)
Piano, Acoustic, Rhythm PopWaltz Ev 085 (B:energetic)
Sax, Tenor, Soloist Jazz Waltz Sw 140

But it doesn't work like that?

When I open the style picker window and search for jazz waltz even feel realtracks, I see only one PopWaltz (with others I already have)
And when I choose this PopWaltz for my song, 2 error messages pop up,

Cannot load drum style, because this folder does not exists.
C:\bb\Drums\PopWaltzEven8^\PopWaltzEven8^3-Hihat,Ride

RealDrums not found (Style) [PopWaltzEven8^3-Hihat, Ride]


Do I have to buy RDs set along with RTs set?
I'm very confused.

Regards,
Jazzutako
