I'm using Menu(3) in my templates to display local navigation, and I'm getting several menus rendered on a single page. That's not exactly what I was expecting, and I can't figure out what's happening from looking at the docs.
My site is broken up into five main sections, each section has several sub-categories, and all my content lives in those categories. I'm three levels down in the tree, so I use Menu(3) navigation within a given section. What I get is the correct navigation menu for the page I'm looking at, plus the menus for siblings of the category I'm in. Is this normal behavior for Menu(), or have I done something horribly wrong?
For example, if my tree looks like this...
|-+ Airplane widgets
|-+ Submarine widgets
...then when I'm in the Airplane Widgets section I get the proper menu for that section, but I also get the menu for the Submarine Widgets section.
