Export shows all black as transparent, even on the character

I’m trying to export an image sequence of PNG4 files, but when I do it shows everything black or dark as transparent. so I have no background which I want, but I also have no clothing because the character wears black, no glasses because they’re black. If something is dark it’s faded. It’s like it’s trying to print the image with no black ink. How do I export the image and keep my lines, black clothes, and other items but leave out the background?
