Custom fields not showing on form

ERPNext Selling/CRM

I added two custom fields and added them on sales invoice form but the fields are not showing on the form.
What needs to be done to make field visible on the form.

@vishwajeets Did you use Customize Form ? or you just added to the DocType?

Thanks for asking. Looks like it was cache issue. I refreshed the page and it started working,
