Nickel Comics. The Dell and Fawcett Comics series are mixed together.
I looked but they aren’t mixed together in Core.
However they dó have the same series title. Is it possible you added them together in your local database?
I created a new collection, then searched for Nickel Comics. It showed two distinct series, one from Dell and one from Fawcett.
I added all the issues to my collection. When I display by Series I see what I shared in my screenshot, the two series blended. If I display by Publisher/Series then they are separated like they should be.
I think maybe the Series Name on one needs to be updated? “Nickel Comics (Dell)”?
