GEOtags have been discarded

Does anyone know what this message is telling me when I upload photos to a new project? See screnshot below:

 

 

Hi Brian,
If the images are to close based on the geotags, they are automatically assigned as similar geotags as mentioned in the warning. This also happens if the GPS of the drone is inaccurate or there are many images taken from the same position. 
Keep in mind that if you do not have image geolocation, you can still process and acquire good results. Then, if you want your model to be scaled, rotated and located, you should measure and mark GCPs in the project.
