Hello,
As we can see, the theme is activated on these sites – http://prntscr.com/107o0m1
According to the ThemeForest license policy, you can use 1 license for 1 project only (dev site, production site, localhost but the same project) – https://themeforest.net/licenses/terms/regular
https://sweetstore.cl/ and https://chefprotein.com/ look like completely different projects. Buy separate licenses for your projects
Regards
