Digging a little bit we discovered that some layouts are searched inside the Joola's templates override foder, where some overrides live, and if not presente they are not picked up in the VM component folder.

user/edit*
manufacturer/default*
manufacturer/details*
The solution by now is to copy the corrispondent original VM templates, that live in the views folder of the VM component, inside the html override folder of the template
