Mozes, you can go to any of your posts and click "EDIT METADATA" and select a higher ISO from the drop down menu.

I suspect different exif viewers are having problems with these large ISO values, and if the exif is causing grief elsewhere, AMASS might pull the incorrect value too. It is safer to just edit the exif on POTN after you upload it. A small hassle but worth it to work around some of these issues.
