Overriding another plugin

We recently installed Klarna Checkout for Woocommerce, and are very pleased with the plugin. Only problem is that it is overriding another plugin (Checkout Files Upload for WooCommerce) in the checkout page. Checkout File disappears, and the customers have no longer an option to add necessary files to their orders.

We have solved the problem temporarily by adding a second payment form, but this is not ideal to us since we only want to use Klarna. We are, however, also depended on the Checkout Files Upload for WooCommerce plugin.

Is there any way to solve this?
