Subscription renewals + licenses manager

Hello, I’m using the YITH WooCommerce Subscription plugin (free) in conjunction with a plugin called License Manager for WooCommerce by WPExperts – ( such plugin lets the user sell license keys using Woocommerce )

I am using your plugin to sell license keys as a subscription product. The issue I’m having is that each license key that is sold gets re-issued once again after a new subscription renews.

I contacted the author of the License Manager for WooCommerce plugin and they advised to contact you guys instead. Any help would be appreciated. Thank you
