Difference between creating a schema manually vs schema through SQL code externally?

[hpant]

I have created a bronze schema manually using catalog->create schema. I have provided external location. The "details" table look like this:

However, when I created silver schema but this time using sql script i.e. 

%sql

CREATE SCHEMA xyz.silver

MANAGED LOCATION '{location}';

The result is same but it has an extra section which is "properties" in "Details" table (highlighted in red color below):

Can anyone help me with this please?
