Up Sell Pop Up takes more space than required

Hi
Im using the up sell feature and the problem is that the pop up takes more space than required. It shows the up sell product images but hides the product name and its cost due to taking more space than required (zoom is at normal level). I’ve tried to solve it through CSS with no result at all.
I’m attaching the sc of how it looks in my computer
Can something be done? I would like my clients to know what the up sell product is and how much it costs so they can buy it now or remember for the future
Greetings
