This sometimes happens when pasting multiples rows and columns directly from Excel.

Generally happens with long datasets (~100 rows). Haven't yet been able to see a pattern with regard to which row it's pasting when failure occurs (2, 10, ...). Always the same row with each dataset, even if all the rows look the same.
