Importing blocks and other features do not work for me

Hello there,

I am not very technical nor good at describing my problems with the correct expressions. I have build large pages with Joomla and Pagebuilder before but maybe I am overlooking something.

1. I cannot trash pages
2. I cannot rename pages, I safe and the old name is back
3. I can import whole layouts but not blocks. When I try to import blocks, I will be asked to buy the pro version.

I have re-installed, re-entered the licence key and I am at my wits end.
I have 4.0.7 Pro
Joomla 4.2.6
Use Win 11 and Microsoft Edge

Thank you for your help.
