When probing analysis results of any kind, balloons pop up with the results on a leader tied to the location.
If any one of them is nudged after the original entity selection, they all fly off generally in the same direction beyond the exent of the model.
They can be moved back to a useful location manually, but thye all fly away again if the entity selection changes.
This has been a bug for at least two years.
