[Risolto] I have a registered WPML account but wpml-string-translation is not updating

Background of the issue:
I have a registered WPML account and I am trying to update the wpml-string-translation component on my site link nascosto. The other components, sitepress-multilingual-cms and wpml-media-translation, are updated correctly.

Symptoms:
I get a message that wpml-string-translation (required version: 3.3.0) is not updating. The message states: 'WPML Update is Incomplete. You are running updated sitepress-multilingual-cms and wpml-media-translation, but the following components are not updated: wpml-string-translation (required version: 3.3.0)'.

Questions:
What's the best way to get WPML to update correctly?
