Nanoradar MR72 ignore parameters

Hello to all
I am using NanoRadar MR72 as a proximity sensor.
The sensor is mounted on the front of the drone and it can see 120 degrees facing itself.
I want to use ignore parameters to detect only 45 degrees forward.

I set the parameters as follows:
PRX_TYPE, 3 (TeraRengerTower)

PRX_IGN_ANG1, 45
PRX_IGN_ANG2, 90
PRX_IGN_ANG3, 315
PRX_IGN_ANG4, 270
PRX_IGN_ANG5, 0
PRX_IGN_ANG6, 0

PRX_IGN_WID1, 45
PRX_IGN_WID2, 45
PRX_IGN_WID3, 45
PRX_IGN_WID4, 45
PRX_IGN_WID5, 0
PRX_IGN_WID6, 0

But it did not work. And I do not see any difference in the performance of the sensor.

Any suggestions and solutions to solve this problem are welcome. Thank you
