I've tried everything, but whenever I try to import a head that isn't the template, the eyes don't import at all. 

I've even tried using a template and just replacing the layers as well as drawing over them, but the result is always the same. 

I'm using Medibang Pro to edit the PSD files because I don't have Photoshop. 

Everything else imports fine, it's JUST the eyes. I can't even replace them in the sprite editor or else they'll just be flat eyes (no iris separation).

Any help?
