Missing ETC Tables

I have been working on a project car for a few years. It is a 2004 L59 5.3 (flexfuel lm7) with DBW in a chevelle. I'm working on installing a LSA blower on it and have it using a COS. Back before the big change from .tun to .ctz I had it up and running. I was looking over the file the other day to get it ready to run with the LSA blower install I'm finishing up.

In my notes and history log in the tune I had made changes to tables B2307 and B2308 which are ETC Pedal Response tables. For some reason these tables have disappeared. Why?

Is it the difference from the old .tun vs the .ctz file type? or did one of the efi live updates simply remove access to these tables for some reason?

I'm guessing those tables are now set to the values I had and I can no longer modify them or return them to stock?

Flashscan must be plugged into your computer before opening a tune file for the ETC folders to display. Nothing changed BTW, that is how its always been.
