Guild Wars 2

I am currently working on getting full seraph gear. I had a blast doing the caladbolg quest and i was excited for an ascended weapon with desired stats.
But sadly there are no seraphic stats to chose from.
Is this an oversight or just on purpose?
I know i can change the stats via mystic forge but i wanna finish the achievemnt of finding all of them which means i transmute it back and forth via magic to get caladbolg origin.

Change the stats (if not an oversight) via the Mystic Forge after you’ve unlocked all the skins/acquired all the weapons?

Good luck.

They usually forget to add the latest stat set to stat selectors. Report it as a bug, and wait few months.
