The detail level is randomly applied when the object is placed. If the "Highest level" is set to 1, and the "Lowest level" is set to 10, then a random detail value will be set between 1 and 10. Copying and pasting an asset retains the detail level of the object copied. If you wish to force a particular detail level, then you need to set both the Highest and Lowest entries to an equal value in the blueprint (ie: 10 and 10, 8 and 8, etc.).
If your in-game detail is set to a lower value than the assets in the route, then those assets will only appear when moused-over. It's not a bug, but a feature and time saving device.
