ERROR in shipping calculation on converted currency and crash with new version

Hello, the plugin performs an erroneous and much higher shipping cost calculation. It applies a very high cost, in all products and shipping fees. This only happens with the converted currency. All other prices are converted OK.

I did conflict test and the error happens with Advanced Dynamic Pricing for WooCommerce PRO plugin activated. Which is not affecting in any way that cost and is an INDISPENSABLE plugin for the operation of my site.

I checked the rules and performed tests by modifying the settings without success.

I tried updating your plugin with the latest version and only got a CRITICAL ERROR (CRASH) on the web. Fortunately I was working on STAGING. I reverted to the original version of the plugin.

In this link you can see a video showing the error on calculation:

Shipping cost its $10 USD, currency rate its 19.90 but calculates like the cost where 178 USD!!!
