SQL Server Xml query with multiple namespaces

The problem
I need to take data from XML files provided by another application. These XMLs contain data that is required to be inserted into tables for a database for a different application.
The problem is this, I can't get the values out of the XML file. I keep getting blank/null values instead.
I am using SQL Server 2014 Management Studio.
What I've tried
I've looked into how to read an XML and have that placed into a table. I've gone as far as looking at tutorials that work. But, whenever I try to apply the same process to my tables and using my XML data I keep getting blank values.
Some help would be appreciated as I have been looking into this for a day and researching how to approach this using MS SQL. And I cannot for the life of me understand why I keep getting nulls.
The XML
<DistributionOrder xmlns="a-url">
<Date>2019-03-07T14:38:00</Date>
<Order_Number>ACME01</Order_Number>
<Comment/>
<Status>Active</Status>
<Lines>
<Line>
<Order_Line_Number>1</Order_Line_Number>
<Product>22</Product>
<Status_Line>Active</Status_Line>
<Comment_Line/>
<Location>ENT_78</Location>
</Line>
</Lines>
</DistributionOrder>
The query
DECLARE #xmlData XML;
INSERT INTO dbo.XMLwithOpenXML(XML_data)
SELECT *
FROM OPENROWSET(BULK 'C:\test_file.xml', SINGLE_BLOB) AS ImportSource;
SELECT * FROM XMLwithOpenXML;
SELECT
element.value('(Order_Line_Number/text())[1]', 'nvarchar(80)') AS Order_Line_Number,
element.value('(Product/text())[1]', 'nvarchar(80)') AS Product
FROM
XMLwithOpenXML
CROSS APPLY
XML_data.nodes('DistributionOrder/Lines/Line') AS DO(element)
GO
What I expect
Order_Line_Number | Product
------------------+----------
1 | 22
What I Get
Order_Line_Number | Product
------------------+----------
|

Figured out that the,
<DistributionOrder xmlns="a-url">
</DistributionOrder>
was the problem. I deleted the xmlns="a-url" from the xml and found that my code is working.
Discovered that you can use
;WITH XMLNAMESPACES(DEFAULT 'a-url')
To take the namespace into account.
