I believe the problem is with the Date field. I'm not an expert, but I believe if you could set up a blend on the date, you could resolve this issue. Someone else can chime in and correct me if I am wrong, because, like I said, I'm not an expert on data blending at this point.
Hi Dominik, This looks like data blending issue. You have to add one or more key in data blending relationship to avoid duplicate values. If you put "tenant" field into the detail then you can see the tenant name instead of asterisks, but obviously duplicates
