It sounds like maybe you imported the images using some imported software and that the data is not coming straight from the SD card.
Please email us a sample image to mapping@dronesmadeeasy.com so we can take a look.
I am not sure how we handle this but the "latitude and longitude : 48,36.3851N / 1,50.8034E and altitude :192,00 (in meters)" part might be the issue. I think all numbers need to be specified with . as the decimal not commas. This is another reason why I think you may have had some software in between the camera and the upload.
