False reading from lidar caused flare too high resulting in stall

Group - I have been using the TeraRanger One Lidar for several months with good success on flying wing drones. However it appears that it sent a false signal to the autopilot on decent that triggered the flare when the fixed wing drone was actually at about 9 meters from the ground. Normally the flare triggers at a much more lower altitude of around one meter or less. The result of the premature flare was a stall and crash. I tested it again with the same results.

A flight log as well as a screen shot are attached.

I would appreciate any insights that any of you have on this issue.
Thank you.
