Looping problem slash bug

Looping problem slash bug

when i have a loop set and stored in a cp, it plays as it should, but when i turn my loop size down to roll, it goes back to the value i had before, meaning it will go striaght to 1/16 or whatever I was at before.

why wouldnt it automatically match the loop size im in so it just goes one down?

hope im clear enough
btw T2 is rockin
