It's a known issue in all 10.14 versions and some 10.15 versions. Apple broke NSOpenPanel when they sandboxed the screensaver pref pane. They also broke window focus BTW.
2 issues can be observed: - you select a file, you get the parent folder. - you switch to the list view mode and you can freeze/crash the System Preferences application. Basically, 10.14 and 10.5 have been huge nightmares when it comes to screen savers.
