Is this position by any chance the edge of the sprite?
I had this problem with the edge of a sprite becoming active for characters several times (in my case with npcs) when I converted the png file to webp.
Did you convert it to webp or is it the png file? Also check there's no loose pixels in the image. VS automatically creates the polygons for characters based on the alpha mask/transpareny in the images.Thanks for replying and helping out!
You could also try exporting the image again from whatever you used or trying different settings. I don't know what settings you used to begin with. In photoshop for example the correct settings for png is 8bit rgb.
