Derived Table name appearing different

Hi All,

I have created a derived table with the name DT_Books in dev instance

but when I check its script in query panel the derived table name is replaced by another name Table_4.

However in Prod instance I can see the same derived table with same definition and when i view the script in query panel the derived table name is displaying appropriately as " DT Books"

Can anybody assist on this

Thanks,
