Node Configuration Edits not saving

I recently noticed when I was trying to edit settings in my Node Configuration that the changes I have been making are not holding. It appears that changes to location (station/offset) are working, but changes to node profile (on grade/sag) and By Pass to Node are not. I will make the changes and hit apply and when I come back to that node, the settings are unchanged. I have also noted that the location align and angle reverted to different settings than I used originally when I placed the nodes, however until now, this was not causing any issues.

Is my .gdf file corrupt, or is there a way to fix this without losing my work?

Thanks!
