I just noticed in my Database that there are a few double ExternalTransactions for orders that got refunded by PayPal between june and july 2020. There is the original refund with the correct paypal ID and also a second one with an other ID. These IDs are in the following format:
The timestamp is pretty random. From a few minutes after the actual refund up to alomst 1 month after. Everything else seems to be the identical between both.
Is this a known bug and is it fixed?
I am using the Trading api via the Java SDK.
