Hello,
View Wishlist you can find in the translation of XStore theme via Loco Translate.
If you face problems with translation, you need to be sure that your translation files are synchronized. Button Sync (Loco Translate plugin http://prntscr.com/glemdq) allows you to synchronize your translation file with pot file.
You can also change text via editing php files via child theme. For example, to change “My account” copy etheme_sign_link function from xstore/framework/theme-functions.php into functions.php of child theme and edit the text there.
Feel free to ask if you have any other questions.
Regards
