Object Fit in Image Collection doesn't seem to work

Dear Community, good morning!

Let’s jump straight in: I’d love to make my images fit inside the specificed image-collection of Webflow’s CMS functionalities. When I specify a fixed value on the height (400px) it shows, but after selecting the necessary ‘Cover’ on the Object Fit, it doesn’t respond.

I’m pretty new to webflow, so maybe I’m missing something, but I really could use the help.
After searching similar topics on “Object Fit” on images within “CMS Image Collections”, and applying those solutions (see image below), I got stranded.

I just cannot get it working. Does anyone might no how to solve this?

Thank you in advance, have a great day!

Kind regards,
Liam
