Hi Christian,
I opened case C41336 for you regarding this. When I looked at your attachment, all of the ComponentIDs on the wire labels look like they could actually be from wire products, e.g. DAT-002, HDM-001. Without a copy of the project with all revisions, this will be difficult to troubleshoot. I will send you separate email asking for the project files.
I am wondering if this is just an issue of not running the report with the filter set to ChangeType = Added. There are certain reports that require the ChangeType filter in order to produce expected results when run against a Delta.
This post shows the list of reports at the bottom.
