Problem with formatting

I’m having a real problem with Scrivener. In a new project, it refuses to indent after hitting return, which is the normal way of starting a new paragraph. I’ve tried settings and even reinstalled but have had no luck. I feel like the solution is simple but I’m not finding it. NOTE - to begin a new project I’ve had to paste text into a blank scene from a past Scrivener project, which tricked the scene into behaving normally. I really don’t want to do that for every scene. I’m on a MAC using 2.6. which seems to be the most updated version I can use with OS 10.9.5
I went through the posts and found nothing that helped. NOTE- I’m not talking about compile, just the normal writing process.
Thanks for any help.
