GST Configuration

I cant able to configure GST HSN Code while creating Item can any one help me

ERPNext comes pre-installed with all 12,000+ HSN Codes so that you can easily select the relevant HSN Code in your Item

https://erpnext.org/docs/user/manual/en/regional/india/gst-setup

I have tried this setup g. . but it is not working

But all you need to do is to select the correct HSN code thats it.
