When adding a constituent to a Constituent List in NXT webview manually, and then trying to either export that list to .csv or as a Static Query in Database view, the manually added constituent does not export in either situation.
We are currently evaluating this issue and will update this article when we have more information.
Steps to Duplicate
Login to NXT webview
Go to Lists > Constituents
Create a constituent list with any filters
Click on the button for Add/Exclude > Add to List
Search for and find any constituent in the database and select them to add them to the list.
Notice that the manually added constituent in Step 5 does not show up in on the main list, only when you click on the number next to "manually added"
Click on Save > In Database View as Static Query or click on the Export option.
Login to Database view
Go to Query
Search for the Query created in NXT webview
Open the query and go to the Outputs tab and add an output for Constituent > Name
Notice the constituent added manually to the list is not present. Also open your .csv file and notice the manually added constituent does not show up there either.
