Summoner weapon not dropping

[Dustytome]

Toss this in the trash bin, apparently I'm just confused as to what all is included in automatic dungeon drops.

Class/Level: SMN 65
Party or solo: Party
Area and coordinates: Bardam's Mettle, Shisui of the Violet Tides
Steps:
1. Run the dungeon on SMN, with all other dungeon pieces collected except the weapon.
2. Finish the run. No SMN weapon placed in inventory.

Additional notes: I have the sch weapon for both of these dungeons and thought perhaps there was something bugging out where it would consider it as the same drop, however I placed the 65 scholar weapon on my retainer and ran Bardam's Mettle again and once again did not receive the summoner weapon despite it being the only piece of summoner gear I have not received.
