Unable to make Copy Vertical tool match the existing stationing from the element to be applied (even checking the Projected box). Have anyone ever experienced something like this?

I am trying to copy a vertical profile into other existing profile matching the stationing, but the Copy Vertical tool is not returning the expected output even when I check the Projected box. I can't use the Project Profile to Element because I need a complex geometry.

The profile on the left should be where the green arrow indicates.

I am also getting this message: "Reference profile is longer than it's plan element". I am not completely sure, but it doesn't seem to reflect what I have.

Thanks for the assistance.
