Why does Uninstall say some relocations stay on the external drive?
Short answer: A few relocations have no kept copy to restore from, so they stay on the external drive. Nothing is lost — copy them back from the drive in Finder whenever you like.
When reverting, the Uninstall wizard puts relocated folders back using the copies Storage Studio kept for each one. A few relocations don't have such a copy, so the wizard leaves those folders on your external drive rather than guess.
Nothing is lost. Open the drive in Finder and copy those folders back to your Mac by hand whenever you like.
