Thank you for providing this additional info. The situation is this:
The Monero coin adapter relies heavily on the subaddresses feature which was introduced in Monero, but is not available in vanilla Cryptonote. Therefore, the coin adapter will only work with forks that have subaddresses. This includes many, but not all Cryptonote wallets.
Unfortunately you will not be able to use karbowanec wallet with this coin adapter at this time.
with regards
