MySQL Workbench auto increment disabled

I am using Workbench version 6.3.5 Community and this is GUI question only.

When creating a new table auto increment check-box is disabled.
Is it a bug or I need to enable this some how in options?
And how to set start value and step for auto increment in GUI when creating a table?

Solution 1:

You need to set auto increment in table

Solution 2:

As a work around, when you click the 'Apply' button and are presented with the generated script to review, you can actually edit that script. I ran into the issue you posted as well and just manually added AUTO_INCREMENT to the column definition I needed it applied to.

Solution 3:

You can do it this way
