Path profile settings unstable

The path Profile menu settings in V26 have become unstable. More specifically, upon drawing a new profile, the Elevation Corridor selection will revert back to Keep Maximum Elevation on Perpendicular rather than Only Sample Exactly Along Path. Also, the checkbox Keep All Original Vertices automatically reverts back to being checked. In fact, it cannot be unchecked. If unchecked, when the profile is exported to csv it retains the original vertices whether the box is checked or not. I had to use V24 to get this job done. Is this a recognised bug with a fix for V26?
