Help with row of pictures

Any one can advise why the 2nd row is split?

You have a few images that are forcing the parent element to be taller than the others. Looks to me that both those images have a parenthesis in the file name that might cause the responsive image generation Webflow does to fail.

You might try uploading those assets without the () to replace the existing ones and republish. You did not share a read-only link to your project so that is the best I can do.
