[PyMOL] APBS surface

Hi everyone,
I am working with a protein-protein complex and I have calculated for each protein, let's say A and B, apbs electrostatic surfaces.
Everything works fine.
My question is:
I have uploaded the structure of protein A and the surface of protein B.
What it shows to me is a "blank" surface for most of the protein A but the part where protein B interact whit it. I think, but I would have confimations, that I am, in some way, "projecting" potential values of protein's  surface B on the surface of protein A, like having a "negative" of the B interactions. It seems it works like this since I know both rotein's interacting residues and now I am facing interacting patch of residues from protein B on their counnter part on protein A.
Am I wrong?

Thank for your answer, in advance,
