Output size wrong with Cli --scale

My sprite sheet original file is of 160x240 pixels. With “–scale 2”, the output should be 320x480. The output png image file is correct. However, the output json file has size of 640x480 in the meta section. Any idea what to do?

the command I used:
./aseprite -b name.aseprite --scale 2 --list-slices --data name.json --layer “layer1” --frame-range [0,0] --save-as name.png

json:
{ “frames”: {
“name 0.aseprite”: {
“frame”: { “x”: 0, “y”: 0, “w”: 320, “h”: 480 },
“spriteSourceSize”: { “x”: 0, “y”: 0, “w”: 320, “h”: 480 },
“sourceSize”: { “w”: 320, “h”: 480 },

},
},
“meta”: {

“size”: { “w”: 640, “h”: 480 }, // SHOULD BE 320, 480
“scale”: “1”,
“slices”: […]
}
