Collection list grid appears horizontal on the Designer but vertical on Live Site

Does anyone know why this is happening? I want the windows to appear as they are in the webflow designer - 3 windows sorted horizontally. Somehow they become sorted vertically on the live site even though I specified 3 columns in the grid parent.

Would love some help and thank you all for your time!
