Return reasons/action inverted

In v2.0 Admin section > Configuration > Order settings > Return request settings:
the values displaied into "Return reasons" and "Return action" are inverted compared to v1.9.

Is this a bug or is this intentional?
If it's a bug, which version is correct?

It's the bug. Thanks for reporting.

Thanks for your reply Andrei.

I'd like to know if the bug is in v1.9 or v2.

Thanks again

No, it's in 2.00
