Start by reproducing the issue in Windows Terminal Preview with Voice Access using the listed steps, and inspect the attached unnecessary-numbers.zip evidence. Trace the Terminal app header's accessibility exposure to determine why three non-actionable numbers receive labels. Done means those numbers no longer appear with “Show numbers” while necessary header controls remain available.
