SACS v5.3 fatigue analysis (warnings questions)

Hi.

I have been trying to make a fatigue analysis and I have some problems with the results of the analysis. First, when I make the dynamic analysis to extract modes and shapes, the result gives me a warning of no unity check option selected. what does it mean and how can I fix it?

then when I make the wave transfer/respond function generation analysis, again the result gives me another warning.
And when I make the fatigue spectral analysis the result gives me a warning of postfile title.
I would appreciate if anyone can help me to solve these problems.
regards
