Duplicate lines

Question

I am trying to edit a polyline in ArcGIS Pro but whenever I make an edit to the line, a duplicate of the line suddenly pops up in my map showing the edit I made in a different location and when I save my edits the line jumps to the wrong location. What is going on?

Looks like some sort of transformation/projection issue on the data. Perhaps the edited data is being projected on the fly, but when you make an edit the "on the fly projection" is being overridden by the underlying coordinate system applied to the data.

It's an idea anyways.

Does it happen with every project or only the current project you’re using?

I would check the coordinate system then. I’ve had something similar happen to me. If it doesn’t happen in other projects it’s not the data (apparently) and if it’s not a projection issue then there’s something funky with the aprx itself.

I think it's a snapping problem. Your line snaps to the closest feature.
