it's a great plugin, and I use the plugin with the ENFOLD theme. The theme supports portfolio items and portfolio categories. The plugins seems to be working fine with the theme, abling me to sort portfolio categories fine, but after a while I discovered a bug.
The sorting function works well, only it hides some of the portfolio categories the longer the list gets. I am able to find them on search, but they don't appear in the list. I increased the number of posts to show on a page, so that can't be the problem.
Any idea what might be causing this, and how to solve it?
