On one of my customer sites, a section on the home page changes without explanation! The site is made with Cornerstone and nothing is used except Cornerstone basic functions.

Page in frontend:
Page in Cornerstone backend:
After saving again, the page is OK in the frontend, but after some time the layout is destroyed again.
