Hi, I am new to the platform so apologies for what I assume is an obtuse question...

When I attempt to duplicate this sample query in the Options Historical Data section of documentation: 

goog = qb.AddOption("GOOG")
goog.SetFilter(-2, 2, timedelta(0), timedelta(180))
option_history = qb.GetOptionHistory(goog.Symbol, datetime(2017, 1, 11, 10, 10),
datetime(2017, 1, 13, 12, 10))
print (option_history.GetExpiryDates())

I do not get the same results as in the sample.

Sample result:

[datetime.datetime(2017, 1, 20, 0, 0), datetime.datetime(2017, 2, 17, 0, 0)]

My result:

[datetime.datetime(2017, 1, 20, 0, 0), datetime.datetime(2017, 2, 17, 0, 0),
datetime.datetime(2017, 3, 17, 0, 0), datetime.datetime(2017, 6, 16, 0, 0)]

Could anyone please let me know where I am going wrong?

Thank you!
