Different names on a different parts of a series > Likes and Comments

Hello librarians,
I have an issue stemming from when I published my two-part series, Mortuous 28, on KDP. Part one, Ashes of Civilization, was under the name Kevin W. K. Moore, with a space between the middle initials. Part two, Echoes of the Ancestors, ended up with a slight difference: Kevin W.K. Moore, without the space between the middle initials. I have since changed it on KPD to the correct author name, Kevin W. K. Moore (with the space), after I noticed the mistake.
I guess I wasn't paying much attention when I started my Goodreads account either. I'm terrible with Goodreads, so I apologize. Either way, I guess I locked into Kevin W.K. Moore without the space in the middle initials. This, in turn, added Part 2 Echoes of the Ancestors into my account. But now, I can't add Part 1, Ashes of Civilization, because it's considered a different author. I don't know how to fix this, and I would appreciate any help anyone can give me.

Now on to the second inquiry. My Goodreads account name also needs to be changed to Kevin W. K. Moore, with the space, if that's possible. Right now it's without the space and that wasn't my intention.

Please let me know how I can go about fixing either of these issues. Thanks so much.
