Disqus and TranslatePress

Hello,

I have the Disqus plugin to insert comments on my website (alicanteabout.com) but there are two problems:

1. In post previous to installing TranslatePress the same English comments are shown to the visitors who select Polish or German languages.
2. New posts published after the installation of TranslatePress don’t show Disqus at all.

What I would like to happen?

Well, I want to show Disqus in all my posts (new and old). The current comments should be only shown to users navigating the website in English. Other languages should have their own set of Disqus comments.

I have been looking around in google but I can’t find a way to fix it.
Can someone maybe help with this?

Thanks a lot!
