Discussion about any issues you are facing with path builder
When I create a path, the path created successfully but when I try to edit that path the last step is not displayed
What do you mean by "the last step is not displayed"?
Does the last step not appear as a dropdown? Or is it disabled? If latter, you can enable it by going to the dropdown on its right.
If it doesn't show up at all, what was your path like? (the classes and properties)
