Dissapearing MIDI track, when adding another MIDI track. (Help?)

[MyNameIsMichael]

When I import a MIDI separately, 1 track at a time, it causes the other MIDI to disappear. (Example, in the picture below, when I import 'A01 MIDI Out', it works, however when I import 'A01 MIDI Out #2' it works, but 'A01 MIDI Out' is replaced with 'A01 MIDI Out #2'. Any ideas? P.S Sometimes on other songs, it doesn't replace it but combines. Which is what I want.

open up 2 3mle and use one to load midis the other one to import tracks and click append tracks when importing multiple tracks so it doesnt erase the previous one
