I am using Nintex Workflow with Sharepoint 2013 OnPrem. I have inherited support for this site. The site is using user defined actions. When I click on the user defined action and the workflow editor opens I cannot edit the action. I can double click on the object but none of the settings appear. All input fields are blank. Almost like it has not been configured. Also the down arrow icon that is on all the objects does not give me any options when I click on it. Any help will be greatly appreciated.
