As the title mentioned, those two class mechanics gets bugged when they are used whilst the player is being a target to CC abilities. Whether from Mobs or other players.
The bug prevents the TR/GWF from activating Stealth/Unstoppable when it occurs.
However it doesn't prevent either from regenerating stealth nor determination.
