Export method gets stalled after a selecting items

-- HikaShop version -- : 2.5.0
-- Joomla version -- : 3.4.3

In the product listing in backend I select all products in page1 (no matter how many items per page) and I do export.

It works.

Then this is over. I cannot advance to next page and not do many things, each time I click in a component button a new export starts.

The only solution is to select another category in the category tree, then go back to the category I was interested and moving to the next page before selecting everything again and doing the next export, and then the problem persists so I have to do again the workaround
