I forgot to "Re-index presets" in Strudio Pro in the Browser (right hand side) the little "house" on the left top row, and an option to "re.index presets" are available further down.
I moved in one of my pitchlists for "Beatbuddy" drums into the folder "Document/Studio Pro/Presets/User Presets/Patch Names" and the did a "Re-index presets"

It seems to work fine it shows up fine in Studio Pro
