... When I used the calculator without turning on the GPS this never happened.

Turning ON the 3.3V GPS switching power supply draws high initial current for some ms, this can affect the circuit if the batteries are relatively low. I think this could be avoided by an external 100uF capacitor between Bat+ and GND near the LP circuit power pins.
