Bug preview webflow

Hi, i have a problem on preview design of the slide show looks good in designer panel and if I try to do preview is also good but when I go and publish website the image jumps down and another About section as well. Is it a bug on Webflow or i was setting not the right dimensions? Thank you.
Here is my site Read-Only: Webflow - Art Gallery

I Upload how it looks like on designer panel and how it looks on publishing stage
