Spoilers are Coming up because you applied reverse thrust.
"Flight spoilers (2 -1/2/3/4/500; 4 -NG's) augment the ailerons and are powered by hydraulic system A (inboard) & B (outboard). Spoilers will continue to operate with speedbrake deployed.
Ground spoilers are also from hydraulic system A.
Only the outboard flight spoilers are powered by hydraulic sys B
On landing, if armed, all spoilers will deploy when the thrust levers are at idle and any two wheels have spun up or right gear is compressed. If not armed, the speedbrakes will deploy when reverse thrust is selected."
