if they're in there, make sure your user name on your pc doesn't have a space in it or there are no spaces in the path. I know this is an issue with the ps2 package creator for the ps4. I think the file that creates the sce_sys folder aside from the keystone is the sc.exe, because it's part of the sc part of the package, which is something that can be removed without a passcode. that's why an official package -- its information can be read even without knowing the passcode. image0 requires the passcode though. it will separate both of them when building the package as not to confuse people, it just lists image0 as the entire package. however, if you try to extract it with pub-chk, it will be separated. sc0 is just sce_sys minus the keystone and possibly the right.sprx, which is the copyright file that appears when you go into I think information or something on the home menu. that is also created by orbis, so it's not needed.
