SP Page Builder Backend and Front End don't save properly

When accessing a page through the backend editor and saving changes, there's inconsistency in whether the modifications are retained or revert to the previous state. This issue extends to the frontend editor as well. This recurring problem has persisted across the last 4 or 5 software versions. It's becoming increasingly frustrating; while backend editing proves effective, the integration of both frontend and backend editing is notably problematic. Awareness of this persistent issue is crucial for a more seamless and reliable user experience.
