Chime debit card ate up a 5/24 slot?

Hello, I recently opened a Chime debit card to help a friend move some money around during an emergency. When he sent the money back to my chime account, I received a new account on my credit report that shows a cash balance equal to the amount I received. This is showing as a secured line of credit. Does that mean I just lost a 5/24 slot? Is there any way I can remedy this? I would have never opened the card if I knew it was going to be treated like a credit card.
