Hello
To amend try adding the following to the Custom CSS field of your templates parameters (Extensions -> Templates -> [YourTemplateStyle] -> Custom CSS)....
[class*=" imghvr-fade"] figcaption, [class^="imghvr-fade"] figcaption {
opacity: 1;
transform: none;
}
.j51imagehover_title {
opacity: 1 !important;
}
