How to complete freebsd-upgrade

[Kenneth Hatteland]

I am following the usual route to obtain FreeBSD 12.0-RC2. But after
downloading and merging the screen only consists of small signs on the
left. Usually hitting end etc will bring me back to a prompt, and I can
proceed with FreeBSD-update install command. But not so after BETA2 which I
am running. How to get past this so I can perform the upgrade _

Blessed be
