Easergy P3 has a dynamic behaviour and will hide functions which are not possible to use e.g. due to missing measurement. Please check your voltage measurement mode initially. Notice also that some of functions might allow to use calculated value but some not. E.g. intermittent earth fault function must have a measured Uo value so a 3LN voltage measurement mode will hide this function.
