currency options not appear in cart and check out

Today I purchased your woocommerce multi-currency plugging and I set up it according to the documentation. But still, I can’t see the option in cart and checkout. And also when the product adds with dollar rate, when we check out that still showing the rupee values even though I selected both currencies as checkout currencies. Please solve this problem.

The site is still at the development stage. I am using Flatsome theme. if you want to sign in authentication I can provide that also.
