Product page changing on refresh

[Shiftypow]

Hi, I recently had my zencart updated to latest patch by someone that used to post plugins on here a long time, there has been several errors since the update and i think due to problems at home has not finished the work even though it has been a month, I have rectified a few myself but I'm not that competent and this is the last problem. I have a problem with the product page layout being fine and then if you refresh a few times or go from product page to product page it seems to break the layout? I have attached two screenshots to show what I mean, I thought maybe there might be a problem with the database but it seems they are in working condition. Any help in advance would be great, thanks.
