Noticed on my titan that my spirit of armamentarium/ophidian class item was causing a bug whenever the game has the player "respawn" (I will refer to this as transmat) whether that occurs after death, between pvp rounds, or even joining allies. You actually start activities with both grenade charges but whenever the game has your character transmat in any way shape or form the the second grenade charge will always go away even if fully charged. No matter how much progress into the second grenade charge, it will completely go down to a single grenade charge with no progress toward the second after any transmat. (Please don't take as long to fix this bug as it took to fix the similar icefall mantle bug)
