When the product quantity is greater than 1, the currency in the shopping cart will be confused

When the number of Japanese currency products is 1, it will be displayed normally. When the number of products in the shopping cart is adjusted to 2, the price of the product will be confused. For example, one is 4800 yen, and the second will become 100 million yen! ! ! !

The same is true for other currencies, but not as exaggerated as the yen.
The single price of other currencies in the shopping cart is displayed normally, and the price of the original product will change when it is greater than 2.
For example, one is 32 euros and two should be 64 euros, but the plug-in shows 27 euros and two are 54 euros, which is a difference of 10 euros.
