However, when I look at the table it's got the OID fields in there. From what I read, the default is set to off, so I don't understand why they're creating them.
The first 7 fields in the image are system fields that are always present but should never be visible. I'd raise a complaint over on pgadmin-support@postgresql.org - or learn the psql utility.
Also,
On the second image you are using double-quotes to delimit a string literal. This is wrong. PostgreSQL always uses single quotes to indicate literal string value double quotes are reserved for object identifiers (table names, column names, etc).
