Automation Not Allowing Alerts to Contacts in Specific Fields + Form Not Adding Lines to the Sheet


I have a 2-fold issue with my Smartsheet. I'm setting up workflow automation, and it's only allowing me to alert one type of contact. See below. I am trying to also add an alert for the registration member assigned to the project.

Additionally, I submitted a test form submission over an hour ago, and it's still not showing up on the sheet. How long does it usually take to populate?
