Issue
When creating a package, certain SharePoint-integrated items may be flagged with an error. Clicking on the error message, you will see the following:
"Multiple ListSettings with the same Category has been found. Unable to package this ListSetting."Resolution
This error can occur when there are duplicate entries for a single list or library on a site collection in the [Integration].[ProcessSharePointSetting] table.
You can check for duplicate entries with the following query:
SELECT * FROM [Integration].[ProcessSharePointSetting] WHERE ListDisplayName LIKE '%<List or Library name>%'
If there is a duplicate, please log a Nintex Support ticket to assist with clean up.
