FMC leg page speeds does not work

The autopilot does not follow my leg speeds.  it was a short trip (ehrd to eham). i had Vnaf en Lnaf on with autopilot and flight director.  fmcspeed was on.  strangely enough the plane didn't follow the leg page speeds.   i never had this before.  it always worked! but now it doesn't strangely enough.

it only works (although it does not follow the speeds in the fmc) if i use the desc climb and cruz buttons on the fmc so i can adjust teh speeds there.

The plane is fully updated.
