I have just been looking through the questions to answer those that I can and as I go to the next page (using the Next button at the bottom) I am presented with the same questions.
I imagine this is not a flaw and in fact questions are coming in fast filling up a page pushing my current page to the next one.
An idea to solve would be to set a variable for starting id when I start paging and only clicking an update button will reset the starting id.
