Synchronize the plugin with “WooCommerce Quick View Pro”

First of all, congratulations on the plugin, it works great.
I have installed it in my store and it works as expected, however I have had a problem that I hope you can help me solve (the web is in construction):
I have the plugin installed next to “WooCommerce Quick View Pro”. The plugin works great in the modal window, but the problem is in the store page. The store displays the products in rows of 3. Each product has a “Quick view” button that shows the product in the modal window and another to add the quantity with your plugin (at the request of the customers there is no “Add to cart” button, the purchase is made directly from the modal window). If I increase the amount from here (for example to 3), when you then click on the “Quick View” button, this amount does not appear added to the plus minus button that appears in the modal window. I can add it from there, but it would need them to be in sync.
Can you help me (please!)?
