I fully agree to Ed Breya. Your Rb standard very probably is not locked, 17ppm off is a typical sign for that.
All such OCXOs (10544 or 10811) can never be out that far, if they are operating correctly (i.e. getting warm, please check).
As both OCXO agree to each other, they seem to be working.
Please check the LOCK signal of your Rb clock.
After you identified the root cause, further hints how to correctly adjusti either of your clocks can be given.
