I don't usually use the Hi/Lo cut control on the Orion, preferring the
BW/PBT alternative but I tried the manoevre Jack, W4TJE suggested and
find mine behaves the same way his does.
I am not certain but what I think is happening is this:
When the Hi/Lo cut knob is rotated the displayed b/w changes as does the
depiction of roofing filter b/w. However, only the roofing filter
selection changes and while the displayed DSP b/w changes it seems the
actual DSP b/w doesn't. That is.....until the Hi/Lo cut control is
depressed for a second or two, whereupon the actual DSP b/w changes to
the displayed b/w. Rather odd and I don't know why it is this way. I
suspect it probably shouldn't be.
The PBT/BW control behaves differently. Changes to the displayed b/w are
immediately reflected in changes in actual DSP b/w and where
appropriate, roofing filter selection. Depressing the PBT/BW control
for a second or two resets PBT to zero.
Seems like this might be something for Ten Tec to look into.

I can;t duplicate this. What does the BW, PBT and RIT readout say before and
after you push the button?
