Currencies are not being updated for some products

Attn: Support

Activated plugin: Woo Commerce Multi Currency Premium (Version 2.1.6.2)
Default Currency: USD

When we run the plugin, the currency values are not getting updated completely and also using geolocation for the currency update.

Case1: If we switch the currency from USD to AED, some products will be showing the values in AED and others remain in USD.
Case2: if we login from different a country, the home page is exhibiting different currencies for different products, i.e. some in USD, some in AED.

Thank you in advance for your help!
