Category display

One more issue here.
When i click a product category through menu on left, i see 21 products per page. When i click a product category through the category option i see 20 products per page. Here is a link so you can see exactly what i mean. Click the category "Accessories" from the menu on the left then from the category listing. merlinsmagicworld.com/index.php/en/magic-shop
I m sending an image to help you understand the issue. Thank you!

Hi,

Go in the menu Display->Content modules and edit each one of your products listing modules and change the number of elements per page to be the same.

again the same problem with the product layout. I see 20 products instead of 21 that i need. Although i changed from the current module on the left from "Display->Content modules" to show 21 products.
What else shoul i do?

On which page do you have that ? Can you provide a link to it ?

i work it on localhost
what information would you need?

We would need to look at the html of the page.
