Styling products in Galapagos template

Site URL: https://www.studiogiraffe.sg/projects

Having two issues with the product page on Galapagos:

1. For some products, the title does not show up on hover. All products have titles so I'm not sure why this is happening. e.g. the purple image in the second row.

2. Is it possible to remove the comma after the product title? I don't want prices to show so I have hidden them, but can't get rid of the comma.

#1. Try adding to Design > Custom CSS

.collection-type-products.view-list.product-info-style-overlay .productlist-item:hover .productlist-title-container {
    opacity: 1 !important;
    display: block !important;
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%,-50%);
    width: 100%;
}

#2. Use this CSS

.productlist-title:after {
    opacity: 0;
}

Thank you so much!
