Confusion about spacers

[strayer]

In the japanese shopping list, there is only one spacer (6mm):

M2×5mm ねじ × 22

M2×8mm ねじ × 6

M2×6mm スペーサー × 14

The english build guide mentions 5mm and 6mm:

Install the 5mm and 6mm spacers from the top。

I assume the shopping list is correct and this is an error in the build guide?
