There's a current issue that I've just spotted on some of my listings when I went to create shipping labels due for shipping today - there is a notification on the listings stating "Refund window closed", with the explainer "Since this order was placed over 180 days ago, it can’t be refunded through the Etsy payment system."
This notification is incorrect as the orders were made in the last fortnight and are only due to be dispatched today.
I'm unsure how many of my orders had this as I only spotted it quite far along in my label creation tasks.
Is this glitch connected to the inexplicable message sent out to sellers last week about outstanding/late orders when they didn't actually have any late orders?
Well it must be a glitch and I would just ignore it unless and until you actually need to refund someone, by which time hopefully it will have resolved itself.
If you can still purchase & print an Etsy label for that particular order, then you should be good to go and I would just ignore the message. Best of luck!
