Adjustable gutter downspout issue

[mason]

I'm building an adjustable gutter downspout and having issues with the adjustable part. I want the top part of the downspout to be adjustable so I can drag the length so that the spout at the bottom is just above grade (which varies from location to location). I got the drag handles to appear but it also moves the bottom of the downspout with it. Can someone help me figure out what I'm doing wrong here? Family is attached.

I don't need the dimension "Below Gutter Straight Section" to be draggable/adjustable. I'd prefer it to be fixed actually, but I can't get the drag handles to show when it's not an instance parameter.

Thanks!

This work?

Thanks @barthbradley! That works. So it looks like you got rid of the reference plane that was at the Ref. Level (0'-0") and replaced it with a reference line (along with some other tweaks). Thanks for your help. The way Revit handles these things seems rather unintuitive to me!

Pipe wouldn't work?

I'm on Revit LT which doesn't have the pipe tool.
