SmartCrawl and WPML - Title tag and Meta description mixed up

Hello,
I have a website that has a german and a russian version (with WPML) and I also use Smart Crawl for SEO.
Additionally I have a Multisite with 7 or 8 different websites.

For the front page I have set up custom Title Tag & Meta Description (directly on the pages) - they differ in german and russian.

When I search for the website on google in german, I get the german Title Tag as it should be. But the Meta Description is russian.

When I search for the website on google in russian, I get the german Title Tag and the russian Meta Description.

Can you let me know, what the problem is?

Thank you
