message persisting in zpool status

A machine (13-stable) has a message like this in 
zpool status -v pool0

This was subsequent to a disk going bad in a mirror (pool0) which was
then removed. it's now a stripe. (I think just removing one half of the
mirror makes it a stripe?)

The message persists despite zpool clear pool0. How can I fix?
