@User_JKLFU Thank you for your advice! That fixed the issue! Thank you again for your help!

Thank you @Luis G! I did need to open that period simply to mark that the email script running on that Item Fulfillment had sent. Otherwise, that customer would continue to get emails every 15 minutes forever. Also Thank you to @Shorin Rio Daa-Oracle for your suggestion!

@Luis G Thank you for the response! How would I open that period if I need to do that?
