SFT-005 REPORTING FOR FD

Hi, 

I hold joint account with my wife in ICICI Bank. I'm the primary account holder and my wife is the 2nd account holder. 

I did some FD from net banking and I see ICICI Bank reported this FD in 26AS/SFT for both of us and it appears in the both 26AS. 

FD certificate was issued in my PAN and TDS was deducted from my PAN only, but SFT shows in both PAN.

This is the only FD that was reported like this, even though I did few FDs in ICICI Bank.

Moreover, this reporting is inconsistent with other banks where I hold joint account with my wife and NO FD was reported to her PAN in SFT, but always in my PAN. 

I think this joint reporting in wrong. 

Even after complaining to ICICI, they said it needs to be reported to both PAN. 

Does anyone know why is it so ? 

Thanks
