ADF4350 Reference Spurs

With the ADF4350 set to 4010.005MHz, INT=200, FRAC=2001, MOD=1 (ref =10MHz, ref doubler on or off), there will be reference spurs when ADF4350 is tuned to multiples of the reference at +/- 5kHz from the carrier output that are only ~40dB down.  This performance doesn't seem to be addressed by the specifications.  Can you please advise?
