Can't manage to see my listings on Amazon from late last night / this morning for some reason

My inventory says listings active but in settings my listing status is inactive.

Only have recieved an email to say my information is being validated as part of a disbursement check. Other than that no warning or email to say why this has happened. I am an established seller. Have spoken to Amazon seller support who have said it might be due to a few pre cancellation orders but just wanted to confirm if anyone else has had this problem and if this was the case..

Also does it automatically go back to normal and how long does it take ? Many thanks
