Updating My View Changes My View Content

I have this view in SQL server:

CREATE VIEW dbo.vwFeat
AS
SELECT dbo.Lk_Feat.Descr, dbo.Lk_Feat.Price, dbo.Lk_Feat.Code, dbo.SubFeat.SubNmbr
FROM dbo.Lk_Feat INNER JOIN
dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt


When ever I open using SQL Entreprise manager to edit it by adding or removing a field i inserts Expr1,2.. and I don t want that. The result I get is:

SELECT dbo.Lk_Feat.Descr AS Expr1, dbo.Lk_Feat.Price AS Expr2, dbo.Lk_Feat.Code AS Expr3, dbo.SubFeat.SubNmbr AS Expr4
FROM dbo.Lk_Feat INNER JOIN
dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt

I don t want Entreprise manager to generate the Expr fields since I use the real fields in my application.
Thanks for help
