[Resolvido] Pagetitel/slug translation after website redesign

Background of the issue:
I have redesigned an existing multilingual website and switched from using WP Global to WPML for translation. The old setup used the English page title/slug with a language code prefix, while the new setup with WPML translates the page title/slug.

Symptoms:
With WPML, the page title/slug is translated, which differs from the previous setup where the English title/slug was used with a language code prefix.

Questions:
How does the translation of page titles/slugs with WPML affect crawling and SEO?
Do I need to set a 301 redirect for each translated language?
