Overshielding in new EX Trial Bug

Date & Time: 8.29.2020 5:11PM EST and 5:17PM EST
Frequency: Twice
World name: Sargatanas
Character name: Jynx Mcninja and Ulan Jun (the ones that were affected)
Monster name: Warrior of Light EX trial
Party or solo: Party
Steps:
1. Party receives the Tank LB3 to survive WoL EX '4 Bar' LB
2. Party receives extra shields to mitigate extra damage
3. 2 of the 8 party members were 'over-shielded' (shielded to the point they had 2 'dots' on their shield meter indicating the amount of over-shielding they had)
4. The 2 party members with the 'over-shielding' are the only ones to die.

This occurred on two different attempts where the first time only one person had the 'over-shield' and they were the only one to die, and the 2nd attempt which was described above.

I have video recordings of the event if needed.
