Xiegu x6100 - Frequency range

Hi. I have a Xiegu x6100 and it’s great to have WFVIEW running now the x6100 has had the WFSERVER update in 1.1.7.
My question is when I try and change the frequency range so it only shows “7.000, 7.200” or “14.000, 14.350” it will default back to a very large range “eg 11 mhz - 18 mhz” on the waterfall which isn’t usable as you can’t see where the individual peaks are.
Am I doing something wrong or is this normal for the Xiegu?

It probably is a bug in the initial implementation.

Thanks - you were and are correct
