Cannot create columns in the menu display

Last week I made adjustments SUCCESSFULLY to the menu, all was good...

Today I made more adjustments, but now I'm receiving an error msg on the top of the page. Any idea on how to fix?

What my client wants:
snipboard.io/EQ8yVm.jpg

Page:
www.chartermachinecompany.com/mm4/

Error message:
snipboard.io/2l8fE0.jpg
