Hello,
That "customer account" it the Joomla account edition page.
You need to configure Joomla and create a menu for that page if you want a better display.
Right now, it's an issue with the menu item id and your template.
Regarding the title in the button, you can see to adjust the buttons via some CSS or change the title of the button using a translation override.
