Some people prefer to keep finances separate. As a case in point, when my ex-wife was applying for AOS (which has been a few moons ago, but not so long that rules would have changed), we had no joint accounts. We did have a child in common, which might have helped. Still - lack of joint bank accounts is not an obstacle if you have sufficient evidence of bona-fide marriage. (I hope this discussion will not turn into the usual pro and con joint accounts - it's an individual matter, and veracity of one's marriage is not decided based on that)

I had a similar situation.  My husband and I have a joint account that his pay is deposited in and that we pay a couple of our bills from.  I also have an account from my previous life that only my name is on and  my pay is deposited in.  I pay most of the bills  or transfer money from this account into our joint account.  At roc I only sent bank statements from our joint account.  ( i sent one from each quarter from the time we married until ROC). If both your names are on the lease send a copy of the lease showing that  instead of showing the rent payment.    We had no problems with this, but i made  sure I included everything I could think of that showed how co-mingled we were.  Wills are great evidence and if you don't have one you should.  (we used Legal Zoom and it was easy and reasonably priced)  Also, send evidence showing each other as beneficiary on life insurance, 401k/retirement plan, health insurance, car insurance cards, etc.  

You get to choose what evidence you want to show. Only show what helps you present a good case.
There's nothing wrong with not disclosing an account.
It would be better - IMO - to have the account shared if you share the funds, but it's not an issue if you don't do things that way either.
