Look at this!
It does not say "trilogy" anywhere on the Jazz CD, which by its booklet appears to be the same as mine. I think the "trilogy" part on the booklet is a mistake made by the cover designers, because while most shareware games are split into three parts, usually one free and the rest only for registered users, Jazz was split into two parts when it first came out (1-3 and 4-6). And the CD art is kind of elaborate for a shareware game. So I'm thinking either it's episodes 1-6 or most likely it's going to be the regular CD version with 1-6, and A, B, C, X, and Z.
