Unexpected large decrease in Total temperature across the shock using sonicFoam

Hi OpenFOAM users!
The past week I have been looking into the possibility to use sonicFoam for some of my Uni work but have been I am experiencing some issues.
Using the tutorial:
For the given case of Ma=3, it was noted that the total temperature seen in ParaView using the Filters->Data Analysis->Calculator and creating a field using this formula
T0 = T + (mag(U))^2 / (2* cp)
Where cp was obtained using data from the thermophysicalProperties file.
There is a significant drop in total temperature across the shock. Also the recovery temperature is also significantly lower then what I would expect.
Can anyone can point out what I am doing wrong?
I do not have this issue if I use the older (no longer part of the official source) rhoSonicFoam - this solver uses defined thermodynamic properties for cp and R. The solver rhoSonicFoam is not attractive to me as I want to use the ePsiThermo Model.
PS: I initially posted this on another part of the forum, not sure if it was the right one. Apologise if you have already read it!
