How to fix issue with “login to Login to See Add to Cart and Prices”

Hello,
On my website https://www.salumeriaitalia.it/en/ I need to hide the price before logging in (I manage this option using this plugin https://wordpress.org/plugins/login-to-see-add-to-cart-and-prices-in-woocommerce/) but if I install your “Price per unit” plugin the recalculated price is shown even before logging in how can I solve this problem?
