Hi @Guleed,
Thanks for describing your issue in detail! I see what could have caused it. It’s most likely related to one of our updates where we moved to the Global CS option. You can read a statement about it on our forum here.
Essentially, it means that if your project was in any geographical coordinate system, this system is replaced with a new option, Global CS. It shouldn’t change any of the actual values. It’s the only way to work in degrees, in geographic systems without datum or height transformations now.
So the fact that your Easting, Northing, and Elevation columns are blank is okay. Your data should be in the Longitude, Latitude, and Ellipsoidal height columns. It should be just the same as it was in October. Please check it. You can upload the project here or share it with me in PM so that I can double-check that everything is fine with it.
Please let me know if you have any remaining questions.
