After installation of Xtra Style PAK 11 and rebuild Styles, the PAK isn't listed "as installed" when German language is selected. All Styles are present and work fine. After changing language to "USA English" the PAK appears in "What add-ons do I have?" and "Show Xtra Styles Set only[]" in the Style-Picker.
