please do a screen recording of like 15 20 seconds and then explain because of language barrier we might not be able to communicate so to save frustration on ur part because i am always ready to help a fellow user, please post a video od what exactly you are facing a problem with.
foe private space and hidden apps , they are both different
private space is swipe left use a lock dedicated for private space as in solely for it and not lock screen and then add apps thereif u accidentally turn on private space completely then just search privatw space in app drawer search to find it again.
hidden icons use the same fingerprint as lock screen one and same password too, and it has a eye with a oblique or slash as icon to hide an app
will wait for you to post video or if this clarifies the issue .
