OnlyOffice Hidden Numbering Rendering Mismatch

What this skill debugs

This skill covers incidents where an uploaded DOCX renders with the wrong list / numbering structure only inside OnlyOffice even though the underlying document is still usable elsewhere.

Typical symptom pattern:

• upload looks fine
• downloaded DOCX still looks fine in Word Desktop
• SpotDraft View Contract or embedded OnlyOffice editor shows extra numbered blank lines or broken hierarchy
• opening the same DOCX in ONLYOFFICE Desktop Editor reproduces the same wrong numbering
• Word can reveal that the source DOCX already contains hidden / latent list formatting that OnlyOffice surfaces more aggressively

This is usually a renderer interpretation mismatch, not backend corruption of contract content.
