I’m facing issue with the w3 total cache plugin

When I activate w3 total cache
Steps to face the issue:
1. Add an item to the cart
2. Switch from INR to USD
3. Go to cart(current currency -> USD)
4. Come back to home page
5. Switch from USD to INR
6. Go to cart(current currency -> INR)
7. Come back to home page

here the currency on the cart will be shown as INR, but the shop currency will be USD
