Price format issues with JPY currency

Hello,

I’m using the plugin in JSON mode and encountering issues with JPY (Japanese Yen) price formatting:
Issue 1: Price format rule not working correctly
I’ve configured the following settings for JPY:
Number of Decimals: 0
Price Format Rule: Range 0-9, Value “0”, Part “Integer”

Problems:
The last digit is displayed as either “0” or “1” instead of all 0

Issue 2: decimals appearing on checkout page
Despite setting decimals to 0 for JPY, prices on the checkout page still show decimal places. How can I ensure JPY prices display without decimals throughout the entire checkout process?

Additional Question:
Is there a shortcode available to display the currently selected currency?

Thanks inadvance
