Its been a common issue which is seeming to come up today (with all models!) where the TP tickbox is becoming unticked in the latest versions
To fix:
Display > Select Consult Registers
Tick the 'TP (load)' or for the NEO engines 'BFuel Schedule (TP)' tickbox to enable load tracing again!
I'll make a fix this week to force it back on!
