Email Assist Task is always closed out when added to a CTA

I'm in the middle of testing the new 5.9 release and came across an issue:

When I create a CTA and add my email assist playbook to it, the checkbox next to
the task is checked and shown as completed even though the task status remains at “Not Started”. The playbook
completion shows 100% complete, but I haven't even sent the email yet. If I did,
then we would see the email stats & bounce rates...




Do we know why this is happening? Glitch?
