Different interest in Cgst and Sgst

My payment of tax of Cgst is more than Sgst so thus on late filing of return my interest payment for late filing return is coming more of cgst than sgst...so problem is i have to pay more interest in case of Sgst which is actually not...but due to auto population of interest of Cgst in tab of Sgst, Im facing problem of paying more interest as same as of Cgst...of Sgst which is not actually as per calculation...
