[CP2K-user] [CP2K:19708] Quantum espresso-like calculation using SIRIUS - output file problem

Dear Aron,

I have found other examples (
https://github.com/dcccc/Plane_Wave_DFT/tree/main/example) that are run 
with cp2k 8.2.
Also in this case, after changing the name of some flags due to the fact 
that I am using cp2. 9.1, I get the same problem: everything runs fine but 
the output does not include all the information it should include.

I attach here my input and output in the case they could be useful. 

Best,
Virginia
