From commit:

Allow the user to process selected queued records, which may or may not have an overlay target selected, without requiring an import action be selected. In the case of records with overlay targets, the import action (overlay selected target) is implicit, so there's no need to select an action.

Additionally, when an import selection has been defined, change the action button from "Upload" to "Import", since we're past the upload stage at this point.
