German translation of the 'Cart' in primary menu

Unfortunately no.

So the issue is that Polylang isn't displaying "Cart" in the currently displayed language? Is it the only text that isn't working?

Yes. These words in woo:
Home
Shop
Cart
Checkout
My account

Can you link me to the page with the "Cart" text?

The content title itself? Can't you change that in the "Pages" area of your Dashboard?

OMG, yes. :)) Sorry for this. It is a sub-installed WP I guess that is why I missed it.

Glad you got it figured out :)
