How to Stop MofNCompleteColumn() from Overflowing in Progress?

[SakiSakiSakiSakiSaki]

import time
from rich.table import Column
from rich.progress import Progress, BarColumn, TextColumn, MofNCompleteColumn, TaskProgressColumn

progress = Progress(
  TextColumn("{task.description}", table_column=Column(ratio=1)),
  BarColumn(bar_width=50, table_column=Column(ratio=2)),
  MofNCompleteColumn(),
  TaskProgressColumn(),
)

with progress:
  task1 = progress.add_task("[red]First", total=100)
  task2 = progress.add_task("[green]Second", total=100)
  task3 = progress.add_task("[cyan]Third", total=100)
  
  while not progress.finished:
    progress.update(task1, advance=0.5) 
    progress.update(task2, advance=0.3)
    progress.update(task3, advance=10.0)
    time.sleep(0.02)

When I run this, First and Third's increment extends past total, until Second is done. What should I do?
