No. The point is that the menu throws to the home page. Under Manage SEF urls not just a link to a category if it is nested categories. When you create the necessary links and linking them to the id menu, call forwarding occurs on the first of the created links. This is a bug in the plugin.

We'll test our extension with latest K2 2.5.4 and let you know.

Hi,
We've just released a new version of our K2 extension. Please update it using the Manage Extensions page in JoomSEF and let me know if it solves your problem.
