Why is my output printing two values?

I want to know why this script is printing two variables even though I specified what I wanted to print. Image Structure of the table;

data = {
	playerName = {
		potato = 0,
		extrapotato = 0
	}
}

The script;

for i, v in pairs(data) do
	print(v.potato) -- outputs: nil 0
	print(v.extrapotato) -- outputs: nil 0
end)

Help? Thanks!

EDIT: I solved it via an admin who told me that I inserted data wrong, all is fixed. :)
