Function Button band up / band down - no rollover

Hi all

i did update to 3.4.21 on 6600M

and

I like the idea of band up and band down function being added to function buttons

BUT

i get unexpected results using them

so the setup is

F1 is Band UP

F2 is Band down

i have two slices open ..slice A and slice B

so i tried band down using F2..and indeed the freq drop down to next lower band freq

so i keep hitting F2 and at one point expected the band to roller from lowest back to highest

NOPE...first thing that happen is Slice B freq went away and B marker goes missing even though panafall is still there...

i reload the profile for two band ssb as before

and

try F1 Band up function

and i get similar response ..slice A does indeed change band

at point of expected band roller over..once again slice B freq goes away

bandup and band down good idea

but

doesnt seem to do roll over when reach the end ...

and

wipeouts other slice

is it my expectation of rollover being wrong ???

and

why did slice B disappear??

and

how do i set it to change slice B and not just slice A?

any insight would be appreciated
