Forgot to sign tax return and was sent a refund check

So my husband and I filed our taxes and they were returned to us 2 weeks ago stating we forgot to sign them. 

 

However, we've now just received a tax refund check very close (but not the same) to what we paid them when we mailed in our tax return originally. Once they get our return back with the signature, will we then owe them again the money they've just returned to us?
