You may have to reset the link for this list/library as per:

Resetting the workflow links

When you need to remove the reuse links, such as if your secondary list is no longer part of the same set of lists and is customized with new columns just for that region, you must reset the list. You can then appify it and it becomes its own solution not linked to other solutions.

For SmartForm links, run the ResetSharePointListFormsUrl method of the SharePoint.Integration.HelperMethods system SmartObject. Use the Site URL and List ID values of the secondary list or library you're resetting as inputs to the method.

For lists and libraries only appified with forms, if you change your primary list from using SmartForms back to using SharePoint forms, you can appify your secondary list or libraries without resetting the form links. See Working with SharePoint Forms for more information on using SharePoint forms.

For workflow links, run the RemoveSharePointDynamicWorkflowLinking method of the SharePoint.Integration.HelperMethods system SmartObject. Use the Site URL and List ID values of the secondary list or library you're resetting as inputs to the method.
