[dba-SQLServer] Import wizard puts data in wrong table

I am using the import wizard to pull text files into SQL Server.  Even
though the wizard very clearly shows that the destination is to be
[dbo].[etc].[conduit] it ends up creating [dbo].[etc].[conduit005] or
[dbo].[etc].[conduit006] etc.  Not all of the time, the first 4 times worked
perfectly but then I end up with the ...005] table.  

Any ideas why, ever seen this etc?

Now I have a ...005] which has no field names [field1], [field2] etc.  All
the data is in the table etc, but no field names because the origin text
files did not have the header row.

Is there any (simple) way to get this appended to the correct table.  This
table has ~400 rows so manually building an append query manually editing
(aliasing) the field names to match is not an option.
