1. I added a 1st medium.
2. I minimized that medium.
3. I added a 2nd medium.
4. Medium #2 was created in a minimized state.
5. I clicked track parser on medium #2.
6. I pasted in 34 tracks' data.
7. I hit hit "parse tracks".
8. I expanded the medium.
Only had the first track had been created and filled out.

I then re-minimized medium #2 and repeated steps 5-8, same result. Only when I had medium #2 expanded while doing steps 5-8 would all 34 tracks be created and filled out.
