What FreeBSD version is this? For some time now, the type for the
virtual consoles is "xterm", not "cons25" or "cons25l1".

Example:

ttyv6   "/usr/libexec/getty Pc"         xterm   onifexists secure

Maybe this file has somehow been excluded from an upgrade process?
I don't have access to a 10.x system at the moment, but I think this
change happened somewhere in 10.x due to sc -> vt...

And it now works? With that (nondefault) /etc/ttys file?
