I loaded up your sitch and then dropped your g10-36.txt TLE file on. The file contains 11 records, and I see 11 satellites, with correct labels?

Fixed. You had a blank line at the start of the file that messed up the parsing. I've made it skip blank lines at the start.

Also fixed a bug where it was not always choosing the best TLE entry

Because I fixed it

I noticed the blank line at the beginning too, and thought it was that (seen it before with other TLE decoders). But was puzzled when it worked just fine. Human race condition

WHOOPS! Sorry! Weird that I managed to do it twice today. I looked at my older TLE files and sure enough, no blanks lines at the start. lol

Thank you!
