Page number starts with 0 on 2nd tab in spreadsheet

Hi,

i have 3 tabs on a spreadsheet. i have headers and footers inserted in to these 3 tabs.

the first tab shows out everything fine - it says “Page 1” at the footer but on the second and third tab, it says “Page 0”

i tried to delete and re apply the item (Under menu → Insert → headers & footers) but it just doesn’t work.

may i have some guidance on what i should do to get the pages to start at “1” instead of “0” on the second and third tab?

thank you.
