Based on the screenshot, it appears you are using an older version of the WPML Plugin. While updating to the latest version is generally safe, I recommend taking a backup of your site first, especially since you are upgrading from a significantly older version to a newer one.
Each update comes with several adjustments and bug fixing, so, always keep the WPML plugin and its addons updated.
Please let me know if you need further assistance in this matter. I will be happy to help.
