Changes cannot be applied and saved:
I try to overwrite the content of the Module "Dylan" but only the Title can be changed.
I cannot overwrite your default demo or blind text.
I now (and yes, I logged out and back in again) cannot even disable rows and save the changes.
In case of new Pages:
The content does "not stick".
I create a new page in Page Builder. link it, and all is good. Add another page, link it and all previously created pages are empty again. And again.
