I am not sure what you are doing in Aspen Plus, but your COFE document contains pure compound properties (not mixture properties) and the property is the temperature dependent vapor pressure correlation for the compound. This is, as a function of temperature, the pressure at which the vapor and the liquid co-exist (so a phase specification does not make sense for this property).
Clearly this property is temperature dependent. You get a better view in COFE if you change the Y axis to logarithmic. The plot that you show below does not make sense for this property - can you double check that you are indeed plotting pure compound vapor pressure?
