Checkout Cash mount

Greetings, we have installed the latest version of the plugin, but in the update in the checkout part we no longer have the possibility of inserting the amount of cash that is delivered and the change that must be delivered to the client, previously the amount field appeared but now it is not possible to view. Likewise, there is a problem in the product search filter, it does not filter properly according to the variants of a product since it includes other products apart from those requested by the filter. I would appreciate the attention The page I need help with: [ log in to see the link]
