Hi,
So please be sure that you right have the latest 2.6.2 HikaShop package and open a thread in the HikaShop forum if the problem is not solved.
The HikaMarket patch is the right one and I cannot reproduce your issue using the patch and the latest build.
But I know that some mistakes has been introduced in HikaShop 2.6.x for the vote system (without being notified and without test with add-ons like HikaMarket)
