Ah, this is a classic case of recipe name not matching the item name. I would consider this more of an Easy Wind Turbine issue, since there is no reason for the internal recipe name to be changed; it should remain the same regardless of the Upgrade setting, just with different ingredients.
I reported it to their side to see if they will fix the bug from their end, since it also causes issues in the Factoripedia, see below:

If they don't fix it from their end, then I guess I could add manual compatibility from my side, but I would rather avoid that case.
