Hi there,

Thanks for contacting us. Sorry for the inconvenience. I had to remove overlay css of image.

added this css code inside the custom.css file.

.sppb-wayne-corp-articles .sppb-addon-article .sppb-article-img-wrap:after {
    content: "";
    position: relative;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    background-color: rgba(18, 19, 48, 0.3);
    border-radius: 3px;
}

-Thanks
