Blood Price giving more MP than intended

Date & Time: 9/3/2017
Frequency: Often/when conditions are met
World name: Excalibur
Character name: Simon Yorke
Retainer name: N/A
NPC name: N/A
Monster name: Sahagin Sapper/Shelfspine Sahagin
Class/Level: Dark Knight/70 (Synced to 49/50)
Party or solo: Party
In-game time: 12:00-12:30 PM PST
Area and coordinates: Western La Noscea
Housing: N/A
Steps:
1. Sync level on fate
2. Draw aggro on as many monsters as possible
3. Activate Blood Price
4. MP returned by the effect of Blood Price becomes far higher than normal. A screenshot, for reference:

(If unable to view - the normal MP returned on-hit at level 49 is 25 MP. The screenshot depicts the MP returns on-hit fluctuating from 1268 to 25 for one hit, then back again.

I haven't tested this without level sync, so I do not know if this is specific to level synced fates or this specific area or not. I was also unable to determine how many monsters must be attacking in order to trigger this bug, but I'm assuming 10+.
