Background of the issue:
Our site is translated to Spanish only using WPML. We have another site using WPML without these issues and have compared many of the settings.
Symptoms:
On PC, the ABOUT menu item does not appear, a button menu item is misaligned, and one item remains in English. On mobile, the same issues occur, and the language selector is misaligned.
Questions:
Why does the ABOUT menu item not appear in the Spanish version?
Why is a button menu item misaligned on PC?
Why is one menu item still in English?
Why is the language selector misaligned on mobile?
