No ferry from Ystad (sweden) to Rønne. Only the other way

If I want to make a route from Denmark to our island Bornholm, and would like to go across Sweden to take the fast ferry from Ystad to Rønne, this is not possible. It forces me back to Denmark to take the ferry from Køge. I have not chosed any “avoid”. If I make the route the opposite way, the app can figure it out and take the ferry from Rønne to Ystad. It seems that the ferry is only in the system as being one-way.
