Page Composer Registration Error

Hi everyone,

I have a problem on Page Composer Registration, when I want to add a new Pages and Sections as a Header/Details I can't save it, Specifically, this problem occurs when I attempt to add more than one page or section. and error is this: Data being added conflicts with existing data.

When adding a new item to the database, the system found a conflicting item already exists.

This problem can happen if another user has entered similar information at the same time as you. Note the changes you have made, cancel the page, then retry your changes.
