Leading zeros are not dropped when using %#d in aqConvert.DateTimeToFormatStr function

I need to remove leading zeros from the day when using date formats e.g. 7/15/1994 instead of 07/15/1994 however when I use the aqConvert.DateTimeToFormatStr function it does not drop the leading zero even though the TestComplete documentation mentions if using the # flag in the format specifier, the leading zeros are removed from the number. (https://support.smartbear.com/testcomplete/docs/reference/program-objects/aqdatetime/date-and-time-format-specifiers.html?sbsearch=leading%20zeros)

 

Here is the code I used (Python): 

DOBField = "DOB - DOD:\n{} - {}".format(aqConvert.DateTimeToFormatStr(Driver.value[3], "%m/%#d/%Y"), aqConvert.DateTimeToFormatStr(Driver.value[6], "%m/%#d/%Y"));

Log.Message(DOBField);

 

The Driver.value[3] and Driver.value[6] is the data that is retrieved from an Excel spreadsheet. The date in these two fields correspond to 7/15/1994 and 6/17/2017. 

 

When I run the script, it logs the following "DOB - DOD:07/15/1994 - 06/17/2017"

 

I expected to get "DOB - DOD:7/15/1994 - 6/17/2017"

 

If I remove the # from the %#d format specifier, it still returns the date with the leading zeros. Can anyone advise what I am doing wrong in my code? Thanks.
