Armor Mod Unresponsive

My armor mod is not responding during mid game swapping. For instance, if I am using Upgraded Thrusters, but then swap to Auto-Medic for a brief period of game play, then want to use Upgraded Thrusters again, my Armor Mod becomes unresponsive. I know this because you are able to sprint and have your shields recharge during this Armor Mod but I will have the Mod active and yet my shield won’t recharge while sprinting. Plus after using this Mod most of the time in my game play I can easily detect when faster sprinting perk that comes with this Mod isn’t active.
