GSTIN not in address field, unable to set up GST

I tried to follow but failed…

The GSTIN field doesn’t pop up. I have the same template as specified.

There’s no HSN Code field too and I am new to ERPNext.

Please tell how to set up GST in this program.

I used the easy install script to install the program today.

This works for me to get the gst fields in the forms/templates.
