Hello, @LMcompany,
1. Yes you can rename it using the theme language files, you have to Install the Loco translate plugin and then edit the theme language file and change the word as per your requirements: https://xstore.helpscoutdocs.com/article/30-base-theme-translation
2- In order to solve your issue simply go to the Dashboard >> XStore >> Theme OPtions >> Theme Custom CSS >> Global and then paste the below code at the bottom of the CSS box there.
@media(min-width:991px){ .product-content .variations_button{flex-wrap:nowrap !important;}}
Then save settings and check back to your site after clearing the browser cache.
Regards 8Themes Team.
