Sorry for the delay, some of us are out on vacation (sadly not me, yet!).
The PhotoshopToSpine script writes each layer as a PNG file. I'm not an artist or Photoshop expert, but you appear to be using clipping mask layers (denoted by the little arrows):

It may be possible for the script to detect that these layers should be merged and merge them automatically, but currently it does not. What you can do is create a group that has [merge] anywhere in the name, then the script will merge all layers in that group, resulting in a single PNG for the group. Eg:
Loading Image
Though you may want to put the [merge] tag in the existing group named TENTBOX (whatever makes sense for what you want as individual PNGs).
