Mget returning same sprite

I generated a map and use mset to update the sprites on the map. But when I tested to print out the sprite number using mget and the coordinates of my cursor, it always returns the same sprite number. I am confused about where I did wrong.

This is what I use for drawing the map and updating.

function draw_game()
	map(0,0,0,0,16,16)
	update_map()
	draw_house()
	draw_cows()
	cow_grazing_anim()
	draw_cursor()
	print("⧗:"..game_time,60,8,1)
end

function update_map()
	for g in all(grass) do
		mset(g.x,g.y,g.s)
	end
end

And I use this to check with mget, it returns all the same sprite number.

if btnp(4) then
			--state=2
			local t=mget(to_grid(cs.x,cs.y))
			printh("x:"..cs.x.."y:"..cs.y..",spr:"..t)
	end

I attached an image with the map I draw and the grass sprite should be from 50 to 53 but I get like all 53 or all 52. which is weird. I have attached my cartridge below, would be great if someone enlighten me on what I did wrong.
