The subscription product does not show the correct currency on the frontend

Hi there, I have subscription products and have 2 different currencies USD and IDR. I used a fixed price for both.

The problem is when it’s in the cart and checkout page, the price is shown as USD even if the currency is symbol correct.

For example, I have a yearly subscription that has 2 prices: $120 and Rp.1.200.000. On the cart and checkout page, when I choose IDR as the currency, it shows Rp. 120.

How to show the correct amount price in the cart and checkout page with the selected currency?

Also, how to show all digits on IDR? for example I want Rp. 1.200.000 will be shown like that instead of Rp. 1.200

Please help.
Thank you
