WP Mission Screen Question

Flying a mission today, and the Air2s tried to arrive at WP2,
but I believe had control signal problem, and could never lock in.
I’m going to run the mission again at a slightly higher altitude.

Question : In the attached screen shot, you see the 2nd speed gauge
with alternating up/down arrow bouncing around at WP2.
Assuming that is the speed at which the drone is moving up/down in altitude
trying to lock into WP2 ?

I ended up cancelling the mission, and did a RTH.
