Disappearing Sidebar Catagories

I've noticed that whenever I add sub-categories to my product categories, I lose the sidebar menu for that category. Basically when I set up a category with more categories listed under that catagory, it disappears from my sidebar menu.

You can see this for yourself you look at my test site at:

Look under the Beer category. You'll notice that ingredients does not display in the left sidebar menu.

Thanks! Any ideas on how to get this to display, please let me know.

Looks good in Firefox browser ...
This is what I see when clicking ingredience under Beer> Ingredients

Here you'll find a variety of ingredients used in making high quality beer. We have many malt products from all around the world.

Some of the subcategories don't show in the categories sidebox, even when you are in that subcat looking at one of its subcats.
(Breadcrumbs: Home :: Beer :: Test :: Grain :: Specialty Malts
Neither Test nor Grain show up in the sidebox, but Specialty Malts does.)

I recall seeing something like this from someone else using this same categories sidebox <ul> mod, though I have no idea what is making it misbehave. Subcats with subcats disappear. That mod also did odd things with the <ul><li> structure, too. You might want to use another mod to handle the categories sidebox. If you know what mod you have now, posting in its support thread would be good.

Thanks guys!

gjh42 -- That's exactly what I'm experiencing. I will have to see if I can't find another mod to handle my sideboxes. I personally use Google Chrome for my browser of choice. I haven't experienced anything funny up until this point.

Thanks for the advice!
