Stranded Inventory first Shipment

My inventory has been stranded for 6 days. The reason stated is “Account not fully onboarded: Your listings are temporarily inactive while they are being prepared for the marketplace.”

This is my first shipment to FBA is this typical? I contacted Amazon help and they were unable to answer any of my questions. I’ve checked my listings for any errors and everything looks good. All listings are active. Thanks for any help!
