ECID values mismatch between Adobe analytics and CJA

Hello community, 
I did come across a problem - 
For example-  if I have MID (ECID) recorded as 123445678 on my desktop when I am on xyz.com website. 
In adobe currently we also track this as a evar, so If I check this in adobe then I would have only 1 unique visitor count

However in CJA - Lets say I use adobe native connector to create datasets for CJA. 
Now since CJA has given me the ability to see the MID directly rather a evar.

If I see all the ECIDs on my evar 12345678 - I got 4 unique visitors because I had 4 ecids recorded on this. 
I am not sure why there were 4, because technically there should be 1. 
If adobe is considering me as 1 visitor but CJA is showing me 4 visitors for the same visitor thats a bummer. 
Not sure what could be the reason. 
Please let me know if anyone found this as a problem or have any thoughts.

Thanks

    ECIDs are read from cookies and might not change across sessions until site data is cleared. So, it is impossible for CJA show different ECIDs unless they are anonymous sessions browsed before the user logged in and identities got stitched together. Also, please note that in CJA you have People metric, which is an equivalent of Unique Visitors in AA.

      @ezhil_raja you are right. 
      I am currently using people dimension but still seeing the discrepancy. I knew stitching happens but dint know ECID would get synced too in AA

      Are you using stitching in CJA?  If so, field-based stitching or graph-based stitching?  In CJA, what ID have you set as your person ID?
