Wrong links to workflow items after adding a new workflow state

After a new workflow state is added in the ZMI, the URL for the state items is missing 'states' in its path.

wrong:
http://localhost:8080/Plone/portal_workflow/my_wflow/test/manage_properties

correct:
http://localhost:8080/Plone/portal_workflow/my_wflow/states/test/manage_properties

This is on:
Plone 5.1.4 (5114)
CMF 2.2.12
Zope 2.13.27
Python 2.7.6 (default, Nov 23 2017, 15:49:48) [GCC 4.8.4]
PIL 5.2.0 (Pillow)

Is the repository address below the correct location to file this bug report?

I would say it's DCWorkflow

Thanks. I just filed the bug report at the link below:
