I looked into the header files.
The My Account link in header is not “hardcoded”.
<a href="<?php echo get_permalink(get_option('woocommerce_myaccount_page_id')); ?>" class="my-account-link"><?php _e('My Account', 'evolve'); ?></a>
As for the WPML translation of the slider. I will have to ask our developers to check it out.
