I am using sshd on FreeBSD 13.2 and it only logs the first line.

Does the second line require some special setting values to be printed?

FreeBSD 13's OpenSSH is based on 8.0p1, which is a bit over four years
old at this point.

No.  It was added in 2022 in this commit, which was first in OpenSSH 8.3:
