Getting an error when using multiple GPIO.wait_for_edge() functions:

Exception in thread Thread-3:
Traceback (most recent call last):

    sbb.readLeftButton()
  File "/home/pi/Smart_Breadboard/Smart_Breadboard.py", line 222, in readLeftButton
    GPIO.wait_for_edge(left_button_pin, GPIO.FALLING)

RuntimeError: Error waiting for edge
  File "/home/pi/Smart_Breadboard/Smart_Breadboard.py", line 225, in readRightButton
    GPIO.wait_for_edge(right_button_pin, GPIO.FALLING)
RuntimeError: Error waiting for edge

This error does not occur when only using 1. I can accurately detect when 1 button is pressed if the other 2 are simulated as timers (not using GPIO.wait_for_edge)
