Daily Sudoku Themes

Since the end of June, My Theme on my Daily Sudoku has been a solid dark blue.  It originally said that the Theme is Spanish Blue Stucco, so I assumed that it was correct.  Then after 50 stars it says it is supposed to be A pat of Flamingos, but it never changed, unless Flamingos are now dark blue and blend in with the background. The preview pane says the next one is Red Stucco, but it stills shows the solid dark blue theme.  Has something changed?  Did I check a box that says do not change theme?  Otherwise, I love this site.
