There's a bug (I think) in the funnel reports right now.
When using a funnel with segmentation (in the "overview" section) , and then switching to another funnel , the segmentation selection remains. By itself it's not an issue, but in fact it DOES NOT actually inflict the segmentation selection (say I selected "registration date" to be between Sept1st and Sept31st) --- the limitation is not affecting the numbers actually shown.
Furthermore - if I try to play with the segmentation filter, nothing happens - the numbers don't change. In order to get this working I need to edit the funnel to "brute force" it to refresh itself.
example:
