I have a list lookup looking into a document library where I need to select multiple documents. In that library is a metadata column I am filtering the list look up by. The filter works and only shows documents with the selection as expected.
However, if I select documents where the filtered column is "A" they are removed from the added side when I change the filter to "B." The filter works to good and is filtering unselected documents as well as selected documents.
Am I doing something wrong, or is this the expected functionality?
