Hello. I answer by myself.
When I create a new page builder module, all is correct.
I have 2 languages. I need modules in spanish and engilsh.
As I said: When I create a new module with (all languages configuration) all is OK.
But when I assign a language and try to Edit the module, the module not load. Page is white try loading....
I use bakcend editor. If I change to frontend editor, 404 page not found.
I think is a problem from the ID when I change de languages.
If I change to all languages configuration in that module created; not work too...
In this case is the FOOTER position module. As you can see you can see the footer spanish module, but not the english footer module:

Please help.
Thank you very much.
