Leviton 3way dimmer #6643 only works with other switch in the up position


I had (2) 3 way switches in my dining room.  They worked fine.


I replaced one of them witha 6643 dimmer.


Now the original 3 way switch acts as an on/off switch & the dimmer acts as a brightness control.


If I flip the original 3 way switch down, the lights go off & I cannot turn them on with the dimmer switch.


Is this the way it is supposed to work????
