Hi Luis,
The screenshots that you have attached are different to the .wsdl that you initially shared, and as said previously you need to modify messages as per your imported xsd's if namespaces are changed.
I have splitted the xsd and the wsdl from the initial wsdl that you provided (refer attached). also i have changed the soap encoded array elements
you can take this as an example and modify other wsdl that you have, also note if your receiver needs the soap encoding, you may still need to use java/xslt to add these
hope this helps
rename PlantaEnvasadoraGLP2.xml to PlantaEnvasadoraGLP2.wsdl
and other files to .xsd
