Just to report a bug:
I usually use Curve with an underlying credit card when I am going to gaz station. The company takes 150€ of deposit and then releases with the correct amount. It is considered by Curve as a refund. Then I go back in time to my debit card (it avoids to block funds on my Lydia account).
Sometimes when I go back in time the transaction disapppear of the time-line…
Also, if the transaction is still in the timeline in the GBIT section it says GBIT to the same card (see screenshot)
