Hi. I have the following design on a Calculation View:

I'm facing a problem with the result of Join_7.
If I check Aggregation_3 and Aggregation_2, I have a dataset which has a unique key:

They Key marked in red is unique. Therefore I expect that, when joining these two aggregations. I can have all measures in one table for further processing.
This is the Join (Inner Join with no cardinality defined):

However, this joing brings the values of ber_menge and bet_wert multiplied by four.

Since there is a one-to-one relation between the two aggregation I expect to have all the values combined, and not multipled. (ber_menge should be 4577 for the first 4 records and 111,2 for records 5 to 8).
All measures in both aggregations are calculated columns, calculated before the aggregations (in previous aggregations or joins) but this only happens with these two measures.
What I tried (with no success):
Any help will be very much appreciated.
