Which scabbard are you using? As I mentioned, I don’t show that you had the appropriate Scabbard. I see a bunch of Awakened (from 60-70), a Weathered (from 40-45) and a Battle-Hardened Scabbard (45-50).
Did you have Timeworn Heirloom Scabbards on a different character? I went through a few and only found the ones I listed.
