I fear you are doing something wrong!

No, it's not showing the day as the month.  You can see this if you 
change the date from 1 to 2 September: your result will still be 
"Jan", not "Feb".

You are doing too much work.  When you extract the month using the 
MONTH() function, you get the result 9 (for September).  So far so 
good.  But you cannot simply display the month name by formatting 
this value as a date, since it is no longer a proper date value.  As 
a date, the value 9 means nine days from day zero - probably 8 
January 1900.  You will see that "Jan" is the correct MMM display for 
this date.

Yes.  The solution is simply to format *the original date value* (or 
a copy of it) as an MMM date.  Alternatively, you could set up an 
array of text values - "Jan", "Feb", and so on - and then use your 
month integer as an index to retrieve the correct month name from the array.

I trust this helps.
