When you create a table that has a column that is both auto increment, and a primary key, and you afterwards try to export a create table script from it, it will remove the auto increment part of it.

Steps to reproduce:

1. Create a table: CREATE TABLE TEST (TEST INT NOT NULL GENERATED ALWAYS AS IDENTITY (START WITH 0, INCREMENT BY 1) PRIMARY KEY);
2. Verify table in objects view > columns
   
3. Right click table TEST > Scripts > Create table script

Expected result: Create table query with a column with both auto increment, and primary key properties
Actual result: Create table query with only a primary key property

This is a property I found now, do not know if other column properties have the same issue
