Caxton Super Hero issues in the latest release

Hi please, it seems to me that some issue occurred after I updated my website (still on the development phase) to the latest release. I here describe the issue: it occurs on the pages I made with superhero background image + super text advise me that that block contains “unexpected content” and I need to convert the block to HTML text in order to have it going on.
While, if I try to build new pages with superhero background image + super text I notice that there are relevant issues: I cannot choose the full-wide image option…
I tried to switch from my child theme to the parent theme (Astra theme) and issues remain.
I ask if there is any fixing…
thank you
