Hi,
I cannot reproduce your issue in the way that I got data stored in the vendor table.
But I saw several problems with the HikaShop vote system ; problems that I asked Xavier to fixed and which seem to be still present.
So I think that the support of votes in the vendor page will be simply removed.
As long as the HikaShop vote/comment system does not follow the requirements I gave, no working integration would be possible.
