How can i fix that when I logout the objects disappear!!!

I create new employee to the company and they appear as I create them and when I logout to signin with this user I can log in normally but as I logout and login again as MxAdmin this object disappear from the list. Autocommitted objects should explicitly have been committed, please check your model and apply the necessary changes. The autocommitted objects have been deleted from the database to prevent database corruption.Number of autocommitted objects per type which still existed for this session: - System.AutoCommitEntry: 1 object(s). - MyFirstModule.CompanyEmployee: 1 object(s).

It looks like you haven't committed your objects. You can use the commit activity in a microflow to save object into your application database so they'll be available next time you log in.
