Topic: Problem with sidebar products

Hello.
I have a problem with the sidebar widget for the product categories.
I made all the categories like this:
1. Products
1.1. High frequency converters
1.1.1. HF compact converters
1.1.2. HF medium power converters
1.1.3. HF high power converters
1.2. Medium frequency converters
1.2.1. MF compact converters
1.2.2. MF medium power converters
1.2.3. MF high power converters
1.3. Hardening machines Subcategory
1.3.1. Vertical scanner machines
1.3.2. Horizontal scanner machines
1.4. High-voltage power supplies
1.5. Special applications
1.6. Components & subassemblies

but only the ones in grey color are listed corectly, and the other ones are list only the subcategories and not the parent.
