Not rounding and counting shipping properly

Hi,

I’ve been testing your plugin, and I’m having difficulties with the final price in cart and checkout. When I have two products (each is 15.99 euro) in cart, the sum get’s rounded to 32. The shipping says 4.65 euro, but the overall final is 36, while it should be 36.63.
Also, the pretty rounding does not seem to be working on the shipping, while the shipping price changes depending on how many digits I choose (e.g. 4.65 compared to 4.8563).

I’ve tried disabling all the plugins besides WooCommerce and your plugin, testing it on the twentytwenty theme, but the error persists.

Do you know, what could be the issue?

Regards,
Marian
