LMG Shield doesn't recharge after it becomes red (low charge)

This issue seems to be reported before but without relevant and required information. Below detailed information and two video evidence can be found.

• Description of Issue -

Retaliator light machine gun's (LMG) shield absorbs damage from enemy runners but doesn't deplete, goes red. Player deactivates shield by pressing Z (on keyboard, default key). Icons on the weapon indicates shield is recharging. After it charges to full capacity, player activates shield again by pressing Z. Shield then shows very low capacity, red color.

This issue seems to not unique to Retaliator, but occurs with Retaliator, Conquest. It may occur with the only HMG in the game but I have no evidence or a memory of that.

I don't remember which shield attachments were used in videos below.

• Expected behaviour is shield to charge when not activated and at hand (seemingly happening), and charged shield to be used when it is activated (not happening).
• Rough Date and Time of issue - March of 29th. After Patch 1.0.5.1.
• Reproduction steps
  

1. Load into a game with a light machine gun with a shield attached to it or pick up a LMG with a shield off of the ground.
2. Equip the LMG. Activate its shield.
3. Get into a fight with it (Videos recorded after fights with enemy runners)
4. Let the shield not deplete completely, but let it go red (Depleted LMG shield may behave the same or differently, I just don't know)
5. While the LMG is still equipped, deactivate its shield. The LMG shield will now seemingly charge.
6. Let it charge to full.
7. Activate shield again.
8. Observe the shield's color and capacity. Capacity won't be full and its color won't be yellow.

Following steps are optional but when they are done, it shows how the LMG shield charge function should work.

1. [OPTIONAL] Drop the weapon.
2. [OPTIONAL] Pick up the dropped weapon and equip it.
3. [OPTIONAL] LMG's shield will charge now. Let it charge to full.
4. [OPTIONAL] Activate its shield. LMG's shield will activate at full capacity and radiate yellow, as it should.

• Notes on Videos in the link below

Both videos are taken moments after fights against enemy runners took place.

Before what is recorded in the second video, I failed to recharge my LMG shield (steps 1-8). Then I tried dropping and picking the weapon, then recharge (Optional steps). Second video shows the optional steps.
