How can I re-enable a dropped JO participant?

Hello community!

I have a simple single email JO program configured to email our execs a weekly summary of some key reports.  It worked fine until I needed to make some changes to the email template.  I forgot that I needed to go into the program and update the tokens in the ‘send email’ stage, so all execs were ‘dropped’ on the next run due to a failure in the send email step.

I have since fixed the send email step and validated both it and the email template itself, then republished the email in the program.  I refreshed the participant list, but it will not reenable the participants.  Is this possible or do I need to create a brand new program to get this going again?  Thanks in advance.
