Klaviyo Review CSS bugs

Hey!

I recently installed Klaviyo Reviews on my Shopify site and I’ve found the ‘All Reviews’ widget styling so buggy. It’s the modal which pops up when you click on an image. I’m a developer so I can add an overflow hidden on the below so that doesn’t happen, but also if there are more than one image the modal scrolls in a big list. I have had a look at the Klaviyo CSS and nothing from my theme is overriding anything. Does anyone have this widget on their site so I can compare the CSS and try to fix? Thanks
