EDIT: I found the problem - see current post.
I must be doing something wrong, but I can't figure out what.
Several weeks ago I set up my first 5 slots in Bank 1 of Performance mode. It was fast and easy. Today I tried copying and pasting some of my rigs from Bank 1 to Bank 2. Basically, I was trying to copy each slot from Bank 1 to its corresponding slot in Bank 2. I was then going to make some small adjustments to each profile in Bank 2. However, when I tried out the Bank 2 profiles, some didn't transfer. Slot 2 was a copy of slot 1, instead of being a copy of its corresponding slot in Bank 1.
I thought I might have just made a copy/paste error, so I did it again. Now (in Bank 2), when I copy a dirty profile onto slot 2, it saves that dirty profile in slot 2 and in slot 1. If I browse through the slot 1 amp stack and change the slot 1 amp to clean and save it, then both slot 1 and slot 2 now have the brand new clean profile.
Any ideas why this might be happening, and how to fix it?
