XnView question

A while back, I used XnView to convert the .dds sprites of Watch Quest! -Heroes of Time- to PNG. I remember they had this weird trim around them that was essentially the last pixels on the end of the sprite being stretched out. After some searching, I figured out how to remove that and be left with only the sprites.

Now, with the same exact game, I ran into the same exact issue. Except I can't remember how I solved it last time.

I thought it had something to do with the alpha channel, but that didn't work this time. Anyone know?
