This sounds quite normal to me, they are quite often more active earlier for the first couple of weeks or so, she's probably well settled in now & will most likely have a nice food hoard in her house so she may be waking up for something to eat from there & coming out again later in the evening or night.
She most likely uses the wheel at night when you're sleeping.
If she gets up really late & you want to get her out for out of cage time then just encourage her out when you can hear that she's awake & see how that goes.
