Currency Switcher Wordpress not displaying correctly?

Question

WordPress

Hello.
Worth the Currency Switcher plugin. The website has multicurrency. 2 currencies. USD and UAH.
When changing the currency to the hryvnia, everything works, when I change it to USD, here is the situation:

The second price instead of the hryvnia shows USD.
The main currency is USD.
Maybe I'm not understanding something, I'm especially new to this plugin.
How to make it show UAH (hryvnia) instead of USD in the second price?
