Shin Megami Tensei Liberation Dx2 ripping problems

[PARCB]

Hello fellow rippers, to my first Tread. I am PARCB, from Spain and it's a pleasure to help this project.
This is in order to ask about certain problems regarding my ripping of the mobile game of SEGA: Shin Megami Tensei Liberation Dx2
EDIT:

1. I have just uploaded the ripped textures.  
   
2. I have entered into some certain issues while ripping the images i wanted (specific "pngs"). It seems that the green layer of the RGBA has noise. How can I get rid of it? I used AssetStudioGUI in order to rip the background and images and this example too. In the attached photos you will see the interface.
   For this I attach the file Example_1.png in order to show the RGBA mix (how the image would be when ripped)
   The Example_R.png is in RA and Example_G.png in GA:
              
   
3. Can someone decrypt the images if i send them?
   

It seems you have to click over the photo to see full-size... I would also like to attach the "example problem" file but it says it is not valid...

I downloaded the data as I play the game on mobile, and I pass the assets to my PC in order to rip them as you see. Almost all of the "pngs" (what I want to rip) gave me this RGB problem; but the "tga" files not at all, those are the best images I could get.
