Duplicated Menu

I have just installed your extension. It's great!

But I found my menus duplicated.

They appear twice:
-With Accordeon Menu CK extension (working ok)
-As usual in Joomla.

How can I avoid the (duplicated) usual Joomla menu?

I've just found the solution.

I had a duplicated module, just had to unpublish it.

Thank you for all.
