harmonic elimination of synchronous motor

I have introduced the synchronous motor into my simulation that contains a 3-phase source, a 3-phase transformer connected to a 3-phase parallel inductive load, and a power factor measurement system . the purpouse of the synchronous motor is to correct the power factor by supplying capacitive power, but the power factor measurements have become very unstable due to the introduction of harmonics. tried to put paralel filter but they are still the same can i get some help and thank you in advance
