Problem with Easy Slider

Good afternoon. I have recently upgraded my website WordPress 5.3 and have noticed that on the pages/posts/portfolio items where I have an Easy Slider at the top of the page, it’s showing blank white space.

I upgraded Enfold to V4.6.3.1 to see if it resolves the problem but it didn’t.

I thought that perhaps it was an issue with Chrome, so I tested it on Firefox and on Safari on my mobile phone and I get the same result.

I have also tested it to see if it affects only blog posts, but it seems pages and portfolio items are affected as well. As all my blog posts and tutorials have an easy slider at the top, I am keen to get this resolved.

Here are blog posts that have an easy slider at the top and they are all showing blank space

Here is a portfolio item that has an easy slider at the top and this is showing a blank space

Here is a page that has some test text, then a slider, then more test text – there is a blank space where the slider should display

Here is a blog post that has an image at the top instead of a slider and that seems to work ok.

Your help would be greatly appreciated. I can provide you login details if you would like to check the back end.
