No "close the gap" today?

Rode Ocean Lava Cliffside Loop this morning on a normal road bike (not TT) just a solo ride, not a workout or event/group ride . My avatar’s hands /position changed as expected when moving in and out of draft but no “close the gap” ???

I have a stereo smart but have had it fora while and recent rides with it have still had “close the gap”

Confused!!

Any thoughts
