Global Typography ignored on translated pages orbilan

Hi

I have created this site using GPP, GBP, Simple CSS and it's looking almost perfect.

I have added the Polylang plugin for providing an EN-version. I have clicked the "Ignore Language" in all the Elements which I have applied to the site.

Now the translated version of our start-page (here's the english version), but the Global typography as defined via Customizer is not being reflected!

Can you please help me fix that?
