Quickview plugins not showing quantity buttons

Hi,
I have tested 2 different plugins for ‘quickview’ in woocommerce:

1) WPC Smart Quick View for WooCommerce
2) YITH WooCommerce Quick View

both came out with a quick view box with a quantity field but no up/down buttons.

with WPC this is what output I am getting:

<form class="cart" action="#" method="post" enctype="multipart/form-data">
	<div class="quantity">
		<label class="screen-reader-text" for="quantity_5c59a27fc41f3">Quantity</label>
		<input type="number" id="quantity_5c59a27fc41f3" class="input-text qty text" step="1" min="1" max="" name="quantity" value="1" title="Qty" size="4" pattern="[0-9]*" inputmode="numeric" aria-labelledby="title of product">
	</div>
		<button type="submit" name="add-to-cart" value="638" class="single_add_to_cart_button button alt">Add to basket</button>
</form>

On the single page view, where the minus / plus buttons are, the full code is:

<form class="cart" action="https://www.randwshop.com/product/blustream-cm100" method="post" enctype="multipart/form-data">
	<div class="quantity">
		<label class="screen-reader-text" for="quantity_5c59a29daa4f0">Quantity</label>
		<input type="button" value="-" class="minus">
                <input type="text" id="quantity_5c59a29daa4f0" class="input-text qty text" step="1" min="1" max="" name="quantity" value="1" title="Qty" size="4" pattern="[0-9]*" inputmode="numeric" aria-labelledby="Blustream HDMI 4K60 Network Controller - CM100 quantity">
               <input type="button" value="+" class="plus">
	</div>
		<button type="submit" name="add-to-cart" value="638" class="single_add_to_cart_button button alt">Add to basket</button>
			</form>

gaining the:
<input type="button" value="-" class="minus">
and
<input type="button" value="+" class="plus">
buttons…

Do you know of a way to load these extra parts in or a better quick view option for enfold which displays all necessary buttons?

Thanks!
