The currency symbol is not displayed

If there is no currency symbol displayed, but square instead, it means that the device doesn't support this exact symbol. To solve this problem you can change the symbol for an alphabetical description, for example: USD, EUR, GBP. Follow these steps:

1. Open application settings and click 'Currency Management'. 

2. Find desired currency and click on its symbol (in your case 'square'). The symbol should be changed to an alphabetic description.
