Productlist looks different after refresh

[EasyBeveiliging]

Hi,

 

I could use some help with my Prestashop website. I'm quite new to all this.

 

Here is an example page of where I have my "problem": http://www.easybeveiliging.nl/58-kluizen

 

If I go to that page the default layout is set on "Raster".

When I click on "Lijst" it looks like a normal list.

When I hit refresh the page my list looks like a combination of the raster and list.

 

Please check out my screenshot in the attachment

 

So I actually like the last option. The raster with the products next to eachother with the short description underneath. How can I make this default? And why is it switching after I refresh the page?

 

Is there a possibility to remove the option to choose? And just make that last option the only default option?

 

Thanks!

 

 

Kind regards,

 

Robbert
