Hi Aleksander,
It seems the bands are missing in MBIM mode and QMI is fine. Please see below
output with MBIM and QMI as well. You will notice that:
1) "Bands" section is missing in MBIM
2) "Modes" section not showing all "supported" options in MBIM
Both of above are correctly shown in an older MM release (1.12.6)
Thanks
MBIM

Could you give here the output of "mmcli -m 0" when running 1.18.2?
