If just disable.... Do you have the enable pins wired up to the drivers?.
Worth a check. Might just be working backwards (low/high) enabled when idle/disabled when wanted. Or on wrong output.
The enable won't drop the holding torque, it will only disable the drive outputs so they don't spin, they will still be locked and he says they drop holding torque and spin when the controller starts up so won't be the enable pins.
