Description (include any images, videos, errors, or crash logs)

When using Chart Editor I met these problems:

1&2. Selection Boxes for hold notes looking like they're overlapped and RAM leaking from having Hold Note Strums (because they have gaps between them?):

2.5. RAM Leaking when staying at the start of the Note Grid:

3. Hold Note Strums increasing RAM Usage insignificantly when being passed through (not sure if fixable but I just found it unintended to happen)

Steps to Reproduce

1. Open Chart Editor
2. Try what I did and place strumlines randomly and leave gaps sometimes between for that to happen 2.5. High RAM Usage/Selection Boxes looking like theyre overlapped
