Spectrum input and Time History input are not interchangable. If you want to run both types of analyses on the same model, I suggest you duplicate the (static) model before entering the dynamic input processor. For example, open "TEST01.C 2" in the static input and "Save As" "TEST01TH.C 2". Then create your response spectrum analysis in "TEST01.C 2" and your time history analysis in "TEST01TH.C 2".
If you already built dynamic data before duplication, I suggest you clear out the existing dynamic input in the second job by opening the model in statics and, while the job is open, delete the ._7 file in that folder (e.g. TEST01TH._7). That will clear out the old dynamic input.
