Posts displayed in double, in a WPML translated network


I am building a bilingual multisite network of e-shops with marketpress and I have enabled the WPML and WPML-marketpress plugins for translation.

I have found the following incompatibility between Recent Posts widget and the WPML plugin:

On the main site, the Recent Posts widget displays the posts in double, i.e. both the original and the translated post.

I would appreciate a solution!
