Downward Lidar ignored in guided mode

In my drone I am using downface lidar for getting correct altitude and keep my altitude stabil but in guided mode arducopter doesn’t use lidar data. I tried it in every mode and just in guided mode lidar becomes useless. Other modes works very well. I enabled terrain follow and I am using mavlink global_position_int to give command. Do you have any idea for my issue?

Thanks for your help.

I have same problem also, Does anyone have a solution suggestion?
