Dynamics in singlet "excited" state

[StKolev]

Does this mean that the two singly occupied orbitals should be alpha
and their energy should be added to that of the system without
scaling? Is this enough for singlet state with 2 unpaired electrons, I
read articles on ROKS and read the help of CP2K but could not
determine this.

Another question, why does it give error when you label the system
singlet? And the system should be labeled triplet to run the
simulation?
