Noise on amp sensor circuit

I have a design that uses 3 amp sensors (current transducers) (two are shown in the schematic). When I first test it out, it works fine. The amp read when the power is off is around 0.03. I am working with two of the sensors. One current draw reads 0.83 when on, the other 1.15.

When I leave it run over time, the ‘resting’ amp reading raises to 0.7 - 0.85. Even after reset, it remains this high.

I am using emon library.

I’ve attached the circuit that I am using. Is there something I should change?
