There might be a couple things here.
Check Settings
Focus
Do Not Disturb
Check if "Smart Activation" is on OR if there is an active "Schedule" outside of the one you said you set (10pm to 7am). If so, turn those off/delete them.
Also, check:
Settings
Focus
"Share Across Devices"...is this on or off? If it's off, your other devices might have a mind of their own.
Do the same thing I suggested above on all devices, if "Share Across Devices" is turned off. I would recommend turning it on, after everything you want is turned on or off/deleted.
