Encrypted swap partition no longer encrypted

Yesterday afternoon I installed FreeBSD-CURRENT to a hard disk drive, 
whilst it was in a dock on USB, and chose encrypted swap.

Then, ZFS send and receive to replicate data from a pool that was on the 
internal drive. Finally, I replaced the internal drive with the one from 
the dock.

Now: swap is not encrypted, this was not my intention.

Might the accident have resulted from an inappropriate change to 
/etc/fstab followed by a swapon command?

I did, at one point, activate and boot the wrong boot environment 
(because `bectl list -c creation` can no longer show the true (original) 
dates of creation of boot environments that were replicated).
