Loginctl and multi-seat desktop: loses seats after first logout

Hello, I am new to multi-seat workstation
I have fedora 35 and gnome-desktop-environment installed,
on boot loginctl shows the correct seat number, and 4 users can connect
[root@srcb02 ~]# loginctl
SESSION UID USER SEAT TTY
11 0 root pts/0
13 4462 ca030 seat-1
15 3886 kb003 seat0 tty3
17 3964 tt002 seat-2
2 0 root seat0 tty2
7 1224 mb0052 seat-3

When they logout I am having black screen and loginctl shows missing seats
[root@srcb02 ~]# loginctl
SESSION UID USER SEAT TTY
11 0 root pts/0
15 3886 kb003 seat0 tty3
2 0 root seat0 tty2

it will work again only when restarting gdm
Anyone Can help?
