Strange observation displaying GPS Tags

Hello,

at first I wish all of you a Merry Christmas and a Happy New Year.

Now let me come to my observation when I displayed GPS tags of my testfile.
Inside this testfile I have 7 GPS tags -- GPSVersionID, GPSLatitudeRef, GPSLatitude, GPSLongitudeRef, GPSLongitude, GPSAltitudeRef and GPSAltitude.

My problem is that sometimes only 4 of the GPS-tags are displayed  -  GPSLatitude, GPSLongitude and GPSAltitude are missing sometimes.

Code:

In order to display the metatags I used the following commands:
Each command starts with -g1 -sep | -charset Latin2
I do not repeat these parameters in the following list of commands.

For the following list of display-commands all 7 GPS-tags are displayed properly:
-all:all
-all:all --composite:all --file:all
-all:all --composite:all --system:all
-all:all --composite:all
-EXIF:all -file:all --system:all

For the following list only 4 GPS-tags are displayed:
-all:all --system:all
-all:all --file:all
-EXIF:all
-EXIF:all -file:all

I had expected that in all cases of used display-commands always all 7 GPS-tags will be displayed. It is not clear to me what I am doing wrong. Please tell me which parameters I have to use in oder to always get all GPS tags. Thanks in advance.

Hello Phil

Thanks for the quick reply.

I will work with -a parameter.
