Have a look at the flow field too, ie velocity and pressure. There’s also a mass imbalance in the Residuals contour group, plot that. If Fluent is struggling to converge the mass balance tends to suffer, if you have a multiphase model on the lost/gained mass may not be the phase you expect. Note, you're only just getting vapour so it's a very small value that you're picking up too.
