pro-gallery unable to read option parameters

I am using an npm package ‘pro-gallery’ in React and trying to get some overlay fade and image hover effects as I did in the playground they provided: My Playground

In the playground I can see those effects but when I do it on my application it doesn’t take affect and I am not sure why. Here is my codesandbox. In the playground generated code, it provided incorrect options object which I corrected on my end but I can’t seem to get the same effect?
