Elementor Slider Issue

Hi. I have 3 slides on the frontpage of my website. I have an issue with one of the slides. Please see the screenshot,

As you can see, the image doesn’t cover the entire slide. It’s also not responsive on a mobile device.

Is it possible to have the entire image fit the slide without the gray background? Please advise. Thank you.
