Most likely because there were some non-printable ASCII symbols in
the Mic-E encoded packet, so they didn't display and you couldn't
copy them to your log. Mic-E format allows use of 3 or 4
non-printable ASCII symbols.
Some trackers allow you to avoid using the non-printable ASCII
symbols. The price you pay is reduced position/speed/course
accuracy in some cases.
