New Database and it has a table `dbo.cmd` already
If your main question is  - why do you already have a table (with data) in a newly created database...?

All newly created Sql Server databases use the MODEL database as a template.  Therefore, I would expect to find dbo.cmd (with the data) already existing in the MODEL database.  Can you verify?

My guess is - someone in the past created dbo.cmd 'accidentally' in the MODEL database.
