Hood locked on 1 side after release with latch is used. How do I open it now? on 2004 Mercedes-Benz CL500

Hi! This is my the first CL-500 and this is the first time this happens. After pulling the latch 2 out of 3 latches are free... the left (if facing the car) is still locked. Tried to mess with it but no success... Ant advice on how I could open my hood?
