ExcelImporter 5.4.1 doesnt set reference

I've often used the ExcelImporter and then set a reference to an object to bundle all imported rows to one collection. This always worked fine, however with ExcelImporter 5.4.1 it seems that the reference is not set anymore. When I inspect the imported objects using an After Commit microflow, the reference is always empty. The object I'm trying to store a reference to is committed to the database before the import action is triggered.
