VirtueMart Search Product with autocomplete in 2 languages

[natax]

Joomla! 3.4.8
VirtueMart 3.0.12
PHP Version    5.5.26

I have Greek & English eshop with VirtueMart Search Product Module with autocomplete.
when you search a product it is showing only the Greek (default) language titles and when you choose one of the results it goes at the Greek home page with "index.php/el/?error=404" at the url

If I switch Search Engine Friendly URLs to No it is working only for the Greek language

Any suggestion please???
