Dupplicate Rows, relationship issues

[Jani9412]

Currently I have this 4 tables I have a dilema. 

"00 Campaign Performance"

"00 Key Master Data"

"00 Targets"

"00 Google ads"

the relationships I have between this situation 

creates me different values for FCT when it should be constants 

and this following  table (which it should be like this)

and when I change the relationship of "00 Campaign perf" to a single direction, the graph I want works and shows how it suppose to be however the table brings me duplicates with the Currency

Wher enow the graph works

But now the table shows like this 

Do you know why is the issue, how could I fix this

Change the bidirectional link to single, merge the Keys and Targets tables.
