Different Look in Preview and Browser, also on another Mac


my layout looks in the Webflow preview differently to when i publish it. The problem just appeared and wasn´t since the beginning. I just checked the published link on another macbook 13 zoll. On this one is everything normal. I just emptied my browsercache (chrome) but nothing happened. Could someone help me? Below the link to the side.

I would be very happy about an answer!
