Ha, caught the cause for myself. One card was just in the demo gyro with me and was deleted by the software because the next one came in. If the model folder of this card is now deleted, the associated data folder receives the information about data deleted by the file yxxxx.vhddel (zero byte length). This shows the delete label on the card.
I just bought a card (from my new friend Carolina Abril 😍 ) and did not notice that it was in the demo roundabout just before, the automatic download did not take place because of the delete flag. So everything is plausible, just download manually and enjoy the gal. 😋
