Modding Help Help with animations!

I was making my item and there was two of them! I think this is a .frames issue. Concerning that I'm new to modding, I wanted to make one. Right after I'm done with this, the mod will go up! Hopefully someone can fix this issue. My .frames reads:

Code:

{
  "frameGrid" : {
    "size" : [42, 16],
    "dimensions" : [14, 1],
    "names" : [
      [ "default.0" ]
    ]
  },

  "aliases" : {
    "default.default" : "default.0"
  }
}

and the image looks like:

 

I can't help you as I know barely anything modding for starbound. But it looks like the one frame thinks it two parts of the sprite sheet. Also, I can't see how it's a good idea to uniquely name something "default"..
