Engagement Program with Recipient Time Zone Showing Exhausted Content
Hello Community!
I'm looking for some guidance as I can't seem to find anything in the standard documentation about Engagement Programs and Recipient Time Zones. One of our Demand Gen team has set up an engagement program that sends emails every 3 weeks on Wednesday at 10am in the recipient's time zone. The program was activated around 10am CT March 8 (with the first cast intended for tomorrow) so it's within the 25 hour window but Marketo allowed it and the earliest time zone being targeted is ET.
While the members have been added to the program and no email has yet been sent, the streams are all showing as exhausted (there's currently only one email in each stream) and the cadence is showing the next stream as March 30 - does Marketo do that preemptively because of the fact that some emails could send out really early if we were targeting the earliest time zones? Here's quick screenshot of what the streams look like at this time (4pm PT):

Spot checking various members within the program, I can see that they all show "Email Send" with tomorrow's date, so we're pretty sure that things will go out as intended, but we wanted to check for future considerations.
Many thanks in advance!
