I have had this issue as well. When you create the listing it shows up blank. The item is still there, but the initial label is gone when you create it.
Yesterday, as far as the issues go, I only had one failed delivery which is much better than the 3 days leading up to it. Luckily the customer repurchased, but it's been frustrating. Hopefully yesterday was a good omen that it's getting better. The day before (April 2nd) i had many more failed deliveries.
