Looks like some combination of things (like an overdue WP Cron job) can lead it to show as next run in "go", which is odd.
Looks like this is caused by a missing type specifier in this sprintf call that handles fuzzy dates in the past tense.
Do we want to handle the next_run indicator differently?
"Next automatic run a couple of hours ago" vs "Next automatic run missed. Please re-run manually."
