categories disappers when on product page

[emax]

Hi everybody,

I am wondering if someone can help me.

I have a websop: www.electromax.nl

 

We are trying out some new stuff, but now the categories block is acting pretty strange.

 

If I click on the first 13 categories, the block strangely disapperas:

 

 

When I click on a product or the last category (Accessoires) the block functions properly.

 

 

 

Any ideas on how to fix this?

 

Any kind of help would me much appreciated.

 

Tnx in advance,

Ömer
