Gabor,
Sorry for the delay. I don’t regularly check the forums.
I did a little bit of research and discovered that the custom post types are NOT public. That seems to be the standard when using the Pagelines Framework and child themes. In my case, Boxes, Banners, and Features should all be showing up under the Post Expiry options, but they don’t. They USED to, but for some reason they disappeared several versions ago.
Thanks for your help!
Brad
