Store menu button question

[Shades]

I'm using the "Ultimate Menu" mod and trying to create sub menus under the "Store" button and it creates the link in admin but it won't add it to the button. I don't have any problems with other mod buttons so I was wondering what would cause this? Is there something in the code thats blocking it from adding sub menus or should I be asking the "Ultimate Menu" author?

I would ask the Ultimate Menu author not familiar with that mod.
