Drone2Map is changing my coordinates when imported into control manager

When I import my CSV file into Drone2Map so that I can link my Ground Control Points, D2M appears to be rounding up the coordinate to the .00000 place.  For Example the project I am currently working on has a GCP located at Lat 38.22145873375075  Long -77.43856540429452.  But when I import the CSV into D2M, it changed the point to Lat 38.22146 Long -77.43857.  This change after processing with D2M seems to be throwing off the Georetification off by over a meter.  Is there anything that I can do to correct this?

Thanks for the note, and I'm glad you were careful enough to notice this.   This is a limitation in version 2.1, and it has been addressed in the upcoming version 2.2, scheduled for release early July.  Drone2Map supports fields for horizontal and vertical accuracy in the GCP files that are input, but until 2.2 is released, the solution for this is to input GCPs in a projected coordinate system. 

If you have ArcGIS Pro, you can reproject your GCPs before ingesting into Drone2Map.
