Does sound strange, but happenned once when my wife purchased via Esty - she was at a friends computer and could not remember paypal password, so she logged in as a guest and funded with CC.

sure once, for convenience, I can understand, but repeatedly buying as a guest??????? wierd

Oh, does the OP do it regularly, I thought it was a one off, sorry putney

If you paid as a guest through paypal you do not get a notification and it is not linked to ebay so is not automatically marked as paid. Have you got a receipt from paypal for the payment?

If a buyer has gone through the eBay checkout system and paid as a guest it is automatically marked as paid on eBay.

The only time it won't be marked as paid is if there is a glitch in the system which happens very rarely.
