Failed Calibration M3M - question

Hello,
I’ve been trying to process an M3M multispectral flight but I noticed that:
(1) the reflectance values are very low, especially in the Green and NIR bands
(2) and although calibration panels were automatically detected, the reflectance factor is the same across all 4 bands.
(3) I used micasense and parrot calibration panels.

This is in Pix4Dmapper.
Any idea what might be the cause of this issue? any kind of help is appreciated!

Did you get any update?
Thanks
