Multi-currency – Approximate price not working with ‘out-of-stock’ products

Hello,
before purchasing your Multi Currency for Woocommerce plugin I installed it’s demo to make sure everything will work fine. Unfortunately when I turned the auto detect: ‘approximate price’ option it works fine for products on stock but does not work for products ‘out of stock’.
The approximated price does not appear below the given price both at category page and product page. I have inventory managing turned off at woocommerce settings and the stock status at the product page is ‘out of stock’.

You can see the problem at the photos from the link below:

Waiting for your reply if it can be fixed soon or it is not possible?

Best wishes,
Niko
