I'm having the same issue
It makes testing so much harder... especially if you need to look at Post-Processed data which adds yet another column for the same hit... it's now very hard to tell "debug" columns from "real" tracking, or to see if there is in fact a duplicate tracking call inflating stats....
I got frustrated and stated using Omnibug... There is a setting there to show redirected entries, or not...
Now, I don't get the redirection if the Debugger isn't open.. but if I need "post-processed" this gives me additional context about how many calls are being made....
The official Adobe debugger has no filtering options that I have seen... I actually had talked with a PM for that tool about 3 years ago, asking for filtering (even just to cut down on the unnecessary rows - either hide or collapse by default, re-ordering important rows closer to the top, etc)... they seemed to like the ideas, but never followed through
