PolyLang string translation for Contac form 7 not working

Hi there,

I have a website that I use PolyLang plugin for translations. I used it before with the same theme and the same plugin and Contaf from 7. But this time I cannot find string translation option for Contact form 7.

Any ideas?
In fact, I see very little string translations than on my other website.

I also installed Loco Translate – but not sure if I have to do anything else then just hit trasnalte plugin or not…nithhg has improved.

Your help in much appreciated
