How to delete unused sync store in box.com ?

I’m syncing DTPO via box.com and it seems to be working fine, except I have an old, unused sync store languishing in box.com (from when I was setting it up).

How do I delete that? Is it OK just to delete it from box.com? Or should I do something from DTPO?

It’s fine to manually delete it as our new Sync engine will not access it.
