The welcome screens in tty are repeated 3 times after booting the system

Hello!
For the first time I came across a strange display of login via tty1.
After starting the system, the login is displayed 3 times, and exactly 4 seconds
pass after the first prompt, and exactly 2 seconds after the second. I did not
change /etc/inittab on my own, and the agetty service also does not start. Below
is what the login replays look like.

This is pc-gentoo (Linux x86_64 6.18.41-gentoo-source) 01:52:35

This is not something critical, but I would like to understand why this is
happening.
I'm sorry if I missed something important, I'm a new user of Gentoo and
GNU/Linux in general. I would be grateful for any help.
