duplicate GST lines under TDS Tax Details

Dear Experts,

Am facing following Issue

1. We have applied GST patch very recently and prior to two years back we have applied India Localization for TDS.

Coming to the Issue

I have a created Payable Standard Invoice and applied GST by going Tools->India Tax Details like i have applied SGST 1.5% and CGST 1.5% and save the form, later on when i go to TDS Tax details, i see the GST lines are duplicated like

Standard Invoice           say 1000

1.   SGST 1.5%     15

2.   CGST 1.5%     15

1.   SGST 1.5%     15

2.   CGST 1.5%     15

Unable to understand on this..

Anyone solution pls.. as we are ahead of going for Production..

Thanks
