What does this LS recredit mean?

I have a question about a refund. I was told that an amount for an item couldn't be debited on time, and somehow the money, or a so-called "SEPA direct debit," couldn't be redeemed and was returned to the payee.

However, the money was debited that same day, and the next day I received an "LS re-credit" for the same amount in my account. I don't understand this, since Rossmann couldn't have received any money from me, could it? Do I owe anyone anything now? I'm very confused.
