Hello,
As it not possible to upload images in this system I will not be able to share any screenshots at all. I could send them by email to your support e-mail address and then you could add it to this case if you want.
My recommendation is that you login to pagebuilder 4.0.8 and create pages and you will see that the author is not updated at all.
I manage this with external scrips directly to the database at the moment as 4.0.8 has severe bugs so the only way is to make some operations directly to the tables in the database as it is not possible to manage from the UIX.
Update the case if you have been able to replicate the issue, I am not alone with this issue, the entire community has the same issue since you introduced new bugs in 4.0.8
