Relaxation mechanism for non-Kramers ion

Dear team

I am doing calculation for getting ab initio blocking barrier for a complex with non-Kramer ion.

So, in the output, I am getting :

MATRIX ELEMENTS BETWEEN STATES WITH OPPOSITE MAGNETIZATION
in cases with even number of electrons, these values cannot be used
check the tunnelling splitting instead

It is mentioned that check the tunnelling splitting but where is it printed in the output. I am not getting that ?
Can anyone help in this regard.
