Taxonomies

Several issues:

1.- I have this message:

Some taxonomies in your site are forced to be untranslatable. This is causing a problem when you're trying to run a multilingual WooCommerce site.
A plugin or the theme are probably doing this.
What you can do:
1. Temporarily disable plugins and see if this message disappears.
2. Temporarily switch the theme and see if this message disappears.
It's best to contact WPML support, tell that you're getting this message and offer to send a Duplicator copy of the site. We will work with the theme/plugin author and fix the problem for good. In the meanwhile, we'll give you a temporary solution, so you're not stuck.

Can you fix the problem?

2.- I don't know hoy to avoid the message askin for mailchimp API key... I don't want Mailchimp at all. How can I remove it?

3.- I also have a message saying that techone have not updated woocommerce templates copies. I'm not sure if I can fixit just copy and paste the original ones from woocommerce.

4.- I have also this message: "Attention: If the settings panel of WOOCS looks incorrect: Clear the browser cashe - read this please. "
But is not fixed following the steps. Can you bring me some help on it?

Thanks in advance.
