--nas-get-rf-band-info not returning correct info for some bands

Hi, I am testing this feature on Sierra Wireless modems (MC7430 currently)
and it has worked on a few bands that I have tried. However, I found that,
at least on band 28, that the command is returning "(null)", whereas
AT!GSTATUS? is returning the correct value, any idea why? Does the
translation below seem correct?
Verbose output:
