+20% PvE Glaive Melee Damage Buff is Not in Effect (at Least to Ultras/Bosses?)

While updating data to reflect the changes in the recent update 8.0.5 over at Quantum Damage-ics, I noticed that glaives did not receive an increase in melee damage to the barrier knights in Witch Queen's The Investigation mission.

While I don't have data for other sources on glaive melee damage, if it didn't apply to these barrier knights then either the buff went out for specific enemy tiers, or it didn't go out at all. My guess is the latter, since they depicted it as a buff in general, ambiguous to enemy combatant tier.

Let me know if you can cross-reference this potential bug and confirm it.
