Low airspeed issue

Hey all,

I'm in the middle of a flight, and decided to try the "time compression" feature. Jut ran it for a minute of 2, then stopped. When I went back to normal time, I received a "Low Airspeed" msg on my fmc. Now I'm noticing this (see attached file). My airspeed is much lower than the fmc commanded speed. I tried moving the throttles (and right now I'm not hooked up to any outside flight controls....just using keyboard) but that didn't help. Any idea as to what is going on?

Many thanks.
