[Plugin: Advanced Category Excluder] Disabling robots doesn’t seem to work

Version of plugin: 1.4.3

I’ve checked the Disable robots option for a category, yet there is no “noindex” nor “nofollow” added to the page and robots still seem to be finding that category (via post views plugin stats).

Saving the source for the category page and running a “diff” on it for both that option checked and unchecked showed that there were no changes made to the page.

For the possibility that it’s theme-related, I’m using Suffusion 3.3.4.
