Game Mechanics: EK Spider Silks not stacking

[Pipkin]

i was in EK tonight trying to get some exp and spider silks and after killing a few thought that i would combine in my kit to make silk swatches. when i looked in my inventory there was only 1 spider silk there. i thought this is strange so i killed another and tried to loot it but still no silks regestered in my inventory. i logged out/in and tried again same thing. the spider silks will not stack for me.[You must be logged in to view images.
