left column not displaying categories correctly

[widget40]

Hi I was just wondering if anyone knows how to change the amount of subcategories can display in the left column before zencart make the subcategorie into a main category.

If that makes sense to anyone. this is how it displays:

main categories:
* Bathrooms
* Home Heating & Ventilation
* Hot Water Heating
* Kitchens & Laundries

then when you click on hot water heating:
* Bathrooms
* Home Heating & Ventilation
* Hot Water Heating
* Continuous Flow Hot Water
* Dairy Hot Water Cylinders
* Gas Hot Water Cylinders
* Hot Water Heat Pumps
* Low Pressure Hot Water Cylinders
* Mains Pressure Hot Water Cylinders
* Valves
* Kitchens & Laundries

do you see that valves has become a main category. I am assuming there is a limit to how many subs cats can be displayed but i cant find out where i can change the limit.

thanks
