Adobe Analytics classifications to CJA

Hello , 
I have a question regarding usage of Adobe classifications in CJA.

I have 4 report suites which has 4 different domains and created a dataflow for all classifications for each report suite. 
However in dataflow for these classifications I am seeing 4 different named component ( ex: age 1 , age 2 , age 3, age 4) in CJA corresponds to each report suite. I thought those would be accommodated as just 1 single component ( ex: age). 
However for metrics ( events) I am seeing only 1 for all report suites aggregated and this is how I would ideally want my classification variable too.
Please let me know if you have any recommendation to fix this.
