Updating language files over and over

Hi,

when I am updating plugins there is also the message that the german woocommerce language files are updated:
Aktualisiere übersetzungen für WooCommerce (de_DE)…

But that does not seem to be successful, cause it happens over and over again.

Is there an easy fix like?
