I selected File/Load Style from Stylepicker and I type Zydeco in the filter string and get nothing.
I too have 2016 PRO and got the same result. But I selected "Show all styles including N/A (not found) Styles" and it comes up. After doing some research, I've concluded that "not found" means "not installed". For me, the Picker shows 858 styles with no filters and 4,902 when I change the option to include "not found".
I'm curious as to how BIAB is able to demo a style that's not installed.
