Okay... I had my MacBook Air, a fairly heavy journal, bag of "stuff" (cables, USB, etc.), an extra vest, some fruit, a water bottle (full), a modest bike kit (allen keys, tape, etc.) in my T-Bag - probably weighed about 10 to 15 lbs in total. I rode pretty hard for a good hour in total over potholes (ouch), railway ties, hard gravel, etc. I have to report that I didn't encounter any looseness or rattling whatsoever. So, I guess your luggage block and/or rack insert is just a little loose.
No shame in being particular about it! I suspect all Brompton owners are very specific about what they want or like - after all, look at the bike we all bought.
