BUG: Ripple Delete Gap Takes Longer As You Continue To Do Them

When I edit my audio in multitrack I cutout everything but good takes. Then I copy them to a new track and ripple delete the gaps in between the remaining good takes. As I do this, it starts to take longer for each ripple delete gap. Relaunching Audition fixes the problem for about 15-20 deletes, then it starts to get exponentially longer for the delete to occur.
