M433 unstoppable force keeps adding back laser in loadout

The M433 with the Unstoppable force keeps adding back the laser and removing the mag flare that i chose. It only happens with this specific version of the M433 for some odd reason. The laser is part of the standard unstoppable force loadout so I guess it overwrites my loadout options or something? The other attachments save as i want them, just the laser keeps coming back and removing the mag flare.
