[Plugin: NextGEN Gallery] Descriptions not updating on category pages

NextGen Gallery 1.9.6, WP 3.4.2, AutoFocus+ Pro theme 1.5.4

When I update descriptions for photos, the description does not update when I’m viewing category pages; it shows an old description. When I go to the actual post with the image, the correct description is shown.

I have no caching plugins.

Example:
https://www.jannebeth.com/category/art-for-sale
(lists incorrect prices in description, for example for “Homestead”)
https://www.jannebeth.com/homestead
(lists correct priced in description)

Help??
