I usually put my 2018 MBP into sleep by closing the lid (without any program open) and next time I only need to open the lid and unlock with fingerprint. However, it recently got an annoying behavior by occasionally shutting down during sleep, forcing me to login with password later.
Here is an excerpt from pmset -g log command:

So, at 3:19 AM the laptop was put to sleep: Entering Sleep state due to 'Clamshell Sleep':TCPKeepAlive=inactive Using Batt
However 3 seconds later there was a wake request from [*proc=powerd request=TCPKATurnOff inDelta=43257]. Also HibernateStats hibmode=0 standbydelay=0.
I really don't know that means. Next time I open the lid at 15:27, this was put in log:

I already disabled Power Nap and Wake for Wifi, tried resetting NVRAM and SMC. Problem still occasionally happen.
Here is pmset -g settings:
