The datasheet gives an offset of 600mV as you've measured. You have to substract it. So for example 600mV is 0A, and 600mV+60mV = 1A, 600mV+120mV=2A etc.
There is also 68 mV noise, but it should be easily reduced with some filtering.
Year, the 600 mv offset is no problem at all - the problem was, that it couldn't measure 0-6 A. The capacitor removed the ripple from the ESC, but the current sensor wasn't too happy about the large capacitance. A normal lowpass-filter with a low capacitance works better
