So I have the same issue with the confused CoL. An additional effect I've seen is that if you change the root part the CoL will centre around this part. There doesn't seem to be an aerodynamic explanation but what do I know. It seems that the calculation of the CoL only takes the root part into account. The other conditions mentioned are the same. (VSR and the engines that are used).

BTW I love the way KKS works. Even during the testing of this KIS/KKS cloning issue I felt the stress of a busted monoprop tank leaking after clone Jeb tumbled into it. The distraction was immense as I tried to save the remaining fuel instead of focusing on my objective. This whilst next to the KSP runway! KKS returns as soon as the clone conspiracy is resolved!

I've seen the same issue of external cloning that is sorted with KKS removal, however it goes further. Once I remove KKS no clone remains outside the pod after boarding but I do get a clone inside the pod when I transfer Krew internally. My Kerbals are all there and appear in their portrait windows with an extra window showing static and the name of the said clone. Access to the cutaway view is disabled as well. Reset to normal is possible with a trip to the space center and back to the craft involved. It's obviously not KKS and I'm working on narrowing down the combination of mods that causes this. Only 96 to go!! I'll update once I know.
