I have a set of 9 arches, grouped together in a group called 'front arches'. When using the wipe effect, for top down or bottom up, the first 2 arches complete the effect, then effect runs across the other 7. If i apply the effect at my 'root group' level so that it wipes down house, trees, mega trees, arches, it behaves as it should. I have tried everything including re-creating the elements, re-mapping them, etc., but when I apply the wipe effect to my arch group, it continues to do the first 2, then the rest of them. Left to right/right to left works fine. Very strange. Any thoughts before I log a bug?

it's worth noting that if I apply the effect to my house outline group, mega tree group(s), etc., it works fine, just seems isolated to arches for some reason..
