Shopping cart button text / translation jumps

Hi there,

i have a problem with the translation of the MY CART text.

Dutch is the default language.
When we switch to English or German, the correct translation is visible for a second, than jumps back to the default language.

We use WooCommerce + Polylang + WooPoly
Any idea how this can happen?
