XML : String Doesnt Delete

I have a string that is called

  <string name="Welcome">             Welcome to The Outlaw's Index! An app designed for individuals who want to educate themselves with knowledge regarding different types of offenses in the United States. Currently this app is directed towards individuals in the United States, but a Canadian version may be released in upcoming months. This app gives users the tools and resources to research different classes of offenses and the repercussions one would receive if convicted. Although this app is informative, advice from law enforcement, attorneys, and other members of the law should be considered more accurate as it may suit your personal needs regarding a specific case. To start off, choose any of the classes on the left hand side, or calculate a sentence and the repercussions that would follow."</string>    

I get the error apostrophe not preceded by \ Even if i place a apostrophe, it removes it and gives me the error again, if i try deleting the whole string, when i try to run the app, it comes back, i tried deleting it, hitting save, and it still doesnt work. The string still comes back. I also have a symbole r cannot be resolved error, but i cannot clean the build or resync the gradle without this issue
