Canna PK 13/14 label confusion!?!?

So I picked up a bottle of Canna PK 13/14. One would think the ratio would be 0-13-14. The label on the back says it contains 0-5-10. The funny thing is that the Canna rep here actually has no idea why.
this from the canna us website:
When CANNA introduced PK 13/14, it used the standard European way to state the NPK ratio. This was expressing percentages of the nutrients in fertilizer as volume/volume (milliliters/ liter). Nowadays, the North American convention of using Mass/mass (milligrams/ kilograms) is the standard and mandatory way to state the NPK ratio's. Therefore CANNA was required to state the mass percentages of the contents of PK, thus the additional numbers 0 - 10 - 11. Same fine product, just a different way of stating the percentages of the nutrients, as 0 - 10 - 11 in mass percentages is exactly the same as 0 - 13 - 14 in volume percentages.
