It's not really specified how do those fields work, but I always thought that having the "Issue" field was a bit redunant with the presence of "Source" field.

I use the second version you showed, I put the issue in "Source" and leave "Issue" blank.

Writing the comic issue in the "Source" field automatically generates in the image the category of said issue. I'm not sure it happens the same if you write the comic issue in the "Issue" field.
