CSV field name aliases when Creating from Portal

Hi there!

When I Create a CSV file from Portal, it creates a .prop file in my print directory that has alias names for some of my field names (which end up in the field name headers of the CSV file created).  This does not happen when creating from LID (it uses the field names from my .rpt as expected).  For the life of me, I cannot determine where these aliases are coming from.  Since I have 2 fields with the same name from different tables (apinvoice, appayment) with the same alias, my CSV file is confusing when the names are replaced like that.  I want to stop the alias replacement in my CSV file.  Is this possible?

Thank you so much!

Here is an example of the alias I am referring to in my .prop file: - where is it getting the text "Vendor ID"?
API-VENDOR name="ApiVendor" alias="Vendor ID" type="Alpha" occurs="1" size="9" decsize="0" row="0" col="9" key="" token="
