IDR Default Currency Rate Exchange

Hello,

We’re using Multi-Currency v Pro and we have a problem with the currency convert rate.
Our store use IDR as default currency. But the currency rate still showing 0.000 for other currency. Screenshot here : https://prnt.sc/13y2lqc
In the product page, the price is showing 0 after switching the currency.

We think that the rate only support until 3 decimal? (1 IDR is around 0.000070 USD).
Can you help us how to fix this?

For simple product, we can cover it by setting the price with fixed price. But we use Woocommerce Booking also. Woocommerce Booking can’t set the fixed price for multi currency. So the available solution is to fix the convert rate exchange.

Please help.
Thank you.
