Smartcrawl vs Yoast SEO : Duplicate content with Weglot

Hello dear community,

I got something for you, forgive me if I just made a mistake on my own I’m not an expert. :sweat_smile:

So, this is what happened: I asked for a SEO audit on a multilingual website using the plugin Weglot for the auto/manual translations. To set the meta description I originally used Smartcrawl. The result of this audit was a lot of duplicate contents due to the meta not translated (during the crawl only) for the different languages. Then I decided to deactivate Smartcrawl, I switched to Yoast, made a quick setting and I asked for a new audit. Not a perfect score but “duplicate content” gone.

Have you heard about this before?
