"Song stats..." are not correctly reset when creating new song

[Marcono1234]

Describe the bug
When creating a new song, the "Song stats..." (under "Settings") are not correctly reset. They still list the blocks from the previous song(s) and also show incorrect percentages.

To Reproduce
Steps to reproduce the behavior:

1. Create a new song and place some notes
2. Create a new song (discard the current one)
3. Look under "Settings" > "Song stats..."
   ❌ It still shows the blocks placed from the first song, with incorrect percentages

Thanks. This is an issue in the reset script, I'll check which bits need to be cleared in a reset.
