When developing in VS Code - problems in apex code are only showing up after I try to deploy. And, if i get multiple problems i can't resolve them all without having to deploy for every problem. As soon as I correct one, the other problems disappear but as soon as I deploy again, the problems/errors in my apex code show up again.

Is there a setting I need to switch?
Is this a bug?
Is this an unintuitive feature?
