With frozenRows method getting different indexes

## Expected Behavior
Frozen 1 row and 1 column should show array from index 0

## Actual Behavior
When I freeze both column and row. I am not getting first value of the array.
I have just commented
func frozenRows(in spreadsheetView: SpreadsheetView) -> Int {
return 1
}
function in one and uncommented in another.

Commented frozenRows method

Please let me know how to deal with this?
