MIDI File Drop Import into Library - 2nd file drop ruins first

Hi.

I believe I may be observing a bug.

Attached is a .zip of two MIDI files.

Drop one into an embedded library and do the MIDI file import process.  The observed result is a clean show of Harmony.

Now drop the 2nd one into the same library.   The 2nd drop will now look good, but the first drop is now destroyed.

Please let me know if the description is insufficient for reproduction, and if so I will make a video.   Thanks!
