Native query greyed out

Hi all,

I am trying to fold my queries, but the View Native Query option is always greyed out, even at source. I am only connecting to SQL server, and not using the SQL statement box in the advanced options as mentioned in this thread: https://community.powerbi.com/t5/Power-Query/View-Native-Query-always-disabled/td-p/1305544 . Still the View Native Query option remains greyed out. I'm not sure why this would be the case?

Don't know if it helps, but these are the steps shown in advanced editor:

let
Source = Sql.Database("server", "database"),
#"dbo_Strong DE$Customer Backconditions" = Source{[Schema="dbo",Item="Table"]}[Data]
in
#"dbo_Strong DE$Customer Backconditions"

Thanks!

Kind Regards,
