Trading cards/Cards inserted the wrong way round.3 messages

In the following series: https: //www.catawiki. nl / catalog / trading-cards / editions-sets / 1164871-marvel-masterpieces-1994

Have a number of cards (not by me) been inserted incorrectly, Back as first and front as second .

The numbers are as follows: 71, 74 to 81, 86, 87, 88, 90 to 97, 101, 115, 126, 127, 130, 131, 135, 137 , 139.

Can this easily be changed by an administrator or do I have to solve this myself by entering new cards everywhere?

Would like to further complete the series with my cards but would beautiful when all cards are in the right place.

Thank you in advance.
