SQL format question

I have a query that runs in my c# program.  I have a full address field in one DB that needs to be parsed and inputted into various fields in another DB.  Here is an example of the full address.

addrLines = '123 Technology Ste. 205 Santa Monica, CA 92675'
This needs to be cut up and inputted into the correct fields in another DB.  For example:

addLine1 = '123 Techology'
addLine2 = 'Ste. 205'
City = 'Santa Monica'
State = 'CA'
Zip = '92675'


When the below query is run inside the program here is my result.

addLine1 = '123 Techology'
addLine2 = 'te. 205'
City = 'Santa Monica'
State = 'CA'
Zip = '92675'

When I run the query using SQL Server Management Studio it works correctly.  When I run the code in the program it cuts off the 1st character in the addLine2 field only.  Every thing else works fine.

Any idea why this might happen?  Here is the query incase you need the info.
