missing output during specific timeframe

sim19

I am trying to run the below formula in Python.

start_date = str(20140901) 
end_date = str(20140701) 
data, error = eikon.get_data("GBSN.PK",  "TR.ClosePrice.calcdate", 
			{"SDate":start_date, "EDate":end_date} ) 
data

Unfortunately, it return an empty dataframe. If I change the start_date to str(20150101) or any later date, it works fine and I do see data for the time period between July and September 2014.

Why is the formula not working for this specific time period?

In case you suspect data is incorrect, please contact the Helpdesk so they can start an investigation.

In Excel:

not quite related, but it seems the start date is later then end date?

When SDate<EDate, the case is incorrectly handled. Please check this link
