Scrolling thru Cabinets Randomly Turns Cabinet to "OFF"

I put the "Cabinet" button in focus..ie Blinking...I start scrolling thru Cab presets and before I know it....the Cab is "OFF"...makes impossible to audition.
To clarify, the Cabinet Button remains flashing (not OFF) but the screen displays (on the left) cabinet, author and (to the right in big letters "OFF"
And is also audibly off.....
What am I doing wrong???
Has been happening thru every update...must be me...
Help!

Got it.
I have been scrolling using "From Rigs"....some of these Cabs WERE turned off.
When I changed to "Local Presets", I had no problem.....WOW!

WRONG!!!...Does the same thing....
Any cab that happens to be turned off in a stored rig will automatically turn off the CAB when selecting from Local or Rig Cabinet Presets.
Quite the oversight and not yet documented (?)

Yes! But I tried it with Auto Load turned off and it does the same thing in Local Presets and From Rigs...weird huh?
No, the Lock button isn't on but that WOULD have been embarrassing.
I had to go thru every preset and turn Cabinet to ON...yuch...
However, scrolling thru the CAB presets now leaves them on and ready to audition.
I think it's either a bug or just never came up before

Good God man, it was made to order!
Too bad I erased all my Local Presets.
