Dear Agatha,
since we’ve made quite some changes to the way the portfolio system works, the desired effect is only possible with the 1-column portfolio page template – I’ve changed the template for the “Limited Edition” page in the “Page Attributes” box (page editor mode) to that one and now the tags do work. If, however, you want them to be identical to the “Photography” page, let me know!
Sincerely,
Andrew | Satori Studio
