Hi Tom,

Did you install your 2018 version over your complete 2017 installation? That should get you close to 6000 styles.

Also, did you try hitting the Clear button at the top of the StylePicker window? It's possible that a filter has been applied to the list, hitting Clear should allow you to see everything.

Once everything's showing up, you can find the Xtra Style PAK content by sorting the StylePicker list by the Set column, and scrolling until you see Xtra PAK in that column.

Thanks
Kent
