PaginationProblem after update joomla 2.5.1to2.5.3

Please i need your help.

I use the free version of hikashop.
I make my eshop with joomla 2.5.1 and everything was perfect.

When i upadate to joomla 2.5.3 i have a very serious problem.
i tried to change a price of a product and after that i do not see all the products.
I see only the results 20-40

I mean that i had 1-20,20-40 and 40-60
Now there is not layout options and i can see only 20-40 results.
Could you please help me.

**********************************
Something curious happened!!!
When i see the page from other pc i could see 0-20,0-40,0-60
when i make the option show me ----> 100
The option of the layout disappeared TOTALLY and now i can see all my product
BUT I THERE IS NO OTHER OPTION TO DISPLAY
*********************************

The problem is front end.
I clear my cookies of my browser and the pagination appeared.
But if i select again for example 50 items it happens again.

What is going wrong?

**it happens when i select more items than i have
**it is very strange that it is not happening when i select show all in that case works ok!
