If your page number from 0 start， change your code : `setFrom(pageNumber*pageSize)`  
If 1，`setFrom((pageNumber-1)*pageSize)`

Please don't post images of text as they are hardly readable and not searchable.

Instead paste the text and format it with `</>` icon. Check the preview window.

Thank you. I noticed this problem yesterday and changed it, but it is not helpful for the second page or even more pages to appear in the data.
