For me, the new Xtra Styles are not showing up when one selects "Xtra Set 11" in the "Show Xtra Style Sets Only" option in the StylePicker Menu. The group appears on the selection list (I have 1-11) the others all show successfully in the StylePicker Menu when I select each other group 1 - 10 individually.

I have refreshed the StylePicker twice, and the new individual styles show in the unsorted menu as Xtra Set 10? Two rebuilds of the Styles have been done, and the program shut down and restarted a few times. This happens in both the 32 bit, and 64 bit versions.

Perhaps they are mislabeled, it would appear the Xtra Set 11 styles are showing up in Xtra Set 10 (which now has 400 styles) !
