Can I see the printscreen of the errors?
I think u added a new language and now u are getting issue for missing caption in the added language.
1.u can opt to fix then.
2.From language-->change anguage in Studio pro to new language and one by one →
click on the error go to element and provide translation
or u can use batch translate too.
If You still want to reset u can version control--->revert all changes if you havent commited.
if u have commited ur changes use version control-->reverse merge changes
