Thanks, I know where is your KB and DEVS documentation. Still there is nothing in there explaining how an order can be modified and what to expect when changing the payment method.

So, the system generates a PayPal transaction ID which has no purpose whatsoever. All right.

Regarding the "bug", I am sure that now that you are aware of it, you will take care of testing and registering it in your opened issues queue.

Thanks again for your valuable help.
