Linen Yarn

[GrimmSpector]

I traded with a village, picked up some "linen yarn (150 ft)", and some "hemp yarn (150 ft)". However, when I try to make cloth, I have the options of Nettle, Flax Linen and Hemp Linen, no just Linen. And when I try either of the Linen options it tells me it's not the right kind. What the heck is this? I'm guessing there's nothing I can do and I've wasted trade resources.
