I'm having these problems too... I put a hold on the Tier 2 Farolin story line because step 4/11 was very hard. Now I'm tier 3, I went back there and step 6/11 asked me to craft 5 Iron chainmail gloves, witch is tier 3 recipe...
If you're doing a tier 2 story line, it should only randomly choose between tier 2 recipes, not from any recipe you do have learned.. It's not fair it would ask some people a tier 1 recipe while for others ask a tier 3, 4 or even tier 5 recipe for the same quest...
