What it looks like is that your Revolut mastercard has been issued under a number scheme for corporate cards and therefore KLM and/or Adyen(or whoever else is currently their payment provider) thinks the card is a corporate card.

You can try looking up the first six numbers of your cards in a BD like https://www.bindb.com/bin-database this one, but it's not guaranteed it will show result (it only shows for a subset of cards).
The fact that it has multiple countries/levels/types attached to the first six number is probably the cause, even though the issuing country is Lithuania. I guess I'll have to contact KLM to correct this issue and I'm afraid it will take some time.
