VarChar problem

I have a SQL query that create a report. Tthis is a part of the query where I bring the Item No.

,LOM.QTY "LOM Qty"
,HK.FIGNUMHK "Fig. No."
,HK.ITEMNOHK "Item No."
,XI.TMNUMBXI "TM No."

My problem is that HK.ITEMNOHK is a Varchar2(4) format

The data look like that
1-8
1-9
1-10
1-11

When I export it to a CSV file it change to data format and I get this

1-8
1-9
1 Oct
1 Nov

Is there a way to force the real value (format)

Open the CSV file with a text editor, not Excel.
