ArcGIS Pro Polyline Vertices revert to original, can not edit existing polyline.

[Anonymous User]

Hello All,

I am running ArcGIS Pro 2.3 on a Windows 10 Desktop.

I can not edit an existing polyline that is drawn in GIS, though I can still create a new feature. When I select a line and to edit the vertices I'm allowed to move and edit the line as I wish but, when I double click to finish the command the line reverts to it's original place.

My workaround is creating a new feature and copying the attributes but the data I am working with is rather large and this can become tedious. 

I did not have any problems until I opened the program this morning. 

Help!

Benjamin - by chance are you clicking the Green Check "Finish" command on the toolbar bottom center of your Map View?  This will finish the sketch and commit the edit.  You may learn more about the workflow here.
