virtuemart pagination problem

[MKI-Miro]

Hi

Time to time there is s problem with pagination.

Example: https://www.puzzlekosice.sk/detske/ine-rozpravky-mix
I should see first 100 products as there is no limitstart variable but I see second 100 products

Or when I click page 2 I can seen limitstart variable in url but i still first 100 products

Joomla 3.7.5
Virtuemart 3.2.4

What should be wrong?
Thanks

https://www.puzzlekosice.sk/detske/ine-rozpravky-mix?language=sk-SK, is not a standard VM/Joomla link, do you use SH404 or other SEF ?
I think that your SEF plugin is the problem not VM
