About ATCC growth kits volume inconsistency - (Jan/12/2012 )

Dear Guys,
I have bought ATCC growth kits for Dermal basal medium, and when I was preparing my medium, my L-glutamine vail conatins higher volume than 15 ml which I should add to my medium (Around 5ml extra).
I contacted the ATCC technical support, and they told me it is overfilled.
But why this over filled and the other bottles in the growth kits are not???
and the vial itself contains 15 ml liter writting
I have attached a photo of my vial
I am sorry guys, I am too skeptic

I wonder if anyone has a similar experience.

The first photo (Shows the remaining solution after taking around 15 ml into my medium)
The second Pic shows the writing on my bottle

I have another growth kits, and I opened it, so every bottle is overfilled, however with a very small quantity (0.1-1 ml) according to original volume (0.5-2ml), however L-Glutamine is over filled with around 6-7 ml, this made me confused.
and what is written on the label too.
so please be careful when u use ATCC growth kits
