By default the Changes.html report that's created as part of the database deployment resource doesn't include identical objects. You can include them by adding a parameter to the New-DlmDatabaseRelease cmdlet or the Octopus Deploy step template.

Using the DLM Automation cmdlets

If you use the DLM Automation cmdlets, in the New-DlmDatabaseRelease cmdlet, add the -IncludeIdenticalsInReport parameter:

New-DlmDatabaseRelease -Source $test -Target $staging -IncludeIdenticalsInReport

Using Octopus Deploy step templates

If you use the Octopus Deploy step templates, in the Create Database Release step template, use the Include identical objects in the change report parameter.
